b=5
therefore y = 5
Answer: y = -2x - 1
Step-by-step explanation:
We can calculate the slope from the two given points. Slope is the change in y per the change in x, sometimes called the rise (y) over the run (x)
Rise is (-9 -3) = -12
Run is (4 - (-2)) = 6
Slope = Rise/Run = -12/6 = -2
The line is y = -2x + b
Find b by using either of the two known points (solutions). I'll choose (-2,3) [because I like smaller numbers]
y = -2x + b
3 = -2*(-2) + b
b = -1 [That was only slightly easier than -9 = -2*(4) + b; b = -1]
The equation is y = -2x - 1

1. A line goes through the points (1, 6) and (–2, 8). Write the equation of the line in Point-Slope form. Show your work algebraically for full credit.
2. A line goes through the points (1, 6) and (–2, 8). Write the equation of the line in Slope-intercept form. Show your work algebraically for full credit. Hint: this is the same line as in #1.
Answer:
1) [tex]y-6=-\frac{2}{3} (x-1)[/tex] and 2) [tex]y=-\frac{2}{3} x+\frac{20}{3}[/tex]
Step-by-step explanation:
Ikr the bots are annoying.
Point-slope form is written as: [tex]y-y_1=m(x-x_1)[/tex]
Slope intercept form is written as: [tex]y=mx+b[/tex]
We also need to find the slope before putting it in this form, which can be done by [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
1) Points given are (1,6) and (-2,8)
Slope: [tex]m=\frac{8-6}{-2-1} =-\frac{2}{3}[/tex]
You can choose either of the two points to put into the formula. I just chose (1,6)
Answer: [tex]y-6=-\frac{2}{3} (x-1)[/tex]
2) Same points as before and we have the same slope as before. All we need is to find the y intercept which is our b in the equation. You can easily do this by plugging in a point and solving for b. I will choose point (1,6) again.
[tex]6=-\frac{2}{3} (1)+b[/tex]
[tex]6=-\frac{2}{3} +b[/tex]
[tex]6+\frac{2}{3}=-\frac{2}{3} +\frac{2}{3} +b[/tex]
[tex]b=6+\frac{2}{3}=\frac{20}{3}[/tex]
Answer: [tex]y=-\frac{2}{3} x+\frac{20}{3}[/tex]

7 divided by 55, but every step must be show
Answer:
Step 1:
Start by setting it up with the divisor 7 on the left side and the dividend 55 on the right side like this:
7 ⟌ 5 5
Step 2:
The divisor (7) goes into the first digit of the dividend (5), 0 time(s). Therefore, put 0 on top:
0
7 ⟌ 5 5
Step 3:
Multiply the divisor by the result in the previous step (7 x 0 = 0) and write that answer below the dividend.
0
7 ⟌ 5 5
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (5 - 0 = 5) and write the answer below.
0
7 ⟌ 5 5
- 0
5
Step 5:
Move down the 2nd digit of the dividend (5) like this:
0
7 ⟌ 5 5
- 0
5 5
Step 6:
The divisor (7) goes into the bottom number (55), 7 time(s). Therefore, put 7 on top:
0 7
7 ⟌ 5 5
- 0
5 5
Step 7:
Multiply the divisor by the result in the previous step (7 x 7 = 49) and write that answer at the bottom:
0 7
7 ⟌ 5 5
- 0
5 5
4 9
Step 8:
Subtract the result in the previous step from the number written above it. (55 - 49 = 6) and write the answer at the bottom.
0 7
7 ⟌ 5 5
- 0
5 5
- 4 9
6
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.

2c–8°, 3c–14°, and c+15°
solve for c
Answer:
Simplifying
c + -2 = 3c + 14
Reorder the terms:
-2 + c = 3c + 14
Reorder the terms:
-2 + c = 14 + 3c
Solving
-2 + c = 14 + 3c
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Add '-3c' to each side of the equation.
-2 + c + -3c = 14 + 3c + -3c
Combine like terms: c + -3c = -2c
-2 + -2c = 14 + 3c + -3c
Combine like terms: 3c + -3c = 0
-2 + -2c = 14 + 0
-2 + -2c = 14
Add '2' to each side of the equation.
-2 + 2 + -2c = 14 + 2
Combine like terms: -2 + 2 = 0
0 + -2c = 14 + 2
-2c = 14 + 2
Combine like terms: 14 + 2 = 16
-2c = 16
Divide each side by '-2'.
c = -8
Simplifying
c = -8

Line f passes through points (8, 7) and (3, 10). Line g passes through points (5, 7) and (10, 4). Are line f and line g parallel or perpendicular?
Answer: Parallel
Step-by-step explanation:
First find slope.
Line f: [tex]\frac{10-7}{3-8} =-3/5[/tex]
Line g: [tex]\frac{4-7}{10-5}=-3/5[/tex]
Since the slopes are the same, the lines are parallel.
First we need to find the slope of each line
Slope of line f
(8 , 7) (3 , 10)
[tex]slope = \frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
[tex]slope = \frac{10-7}{3-8}[/tex]
[tex]slope = \frac{3}{-5}[/tex]
[tex]slope=-\frac{3}{5}[/tex]
Slope of line g
(5 , 7) (10 , 4)
[tex]slope = \frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
[tex]slope = \frac{4-7}{10-5}[/tex]
[tex]slope = \frac{-3}{5}[/tex]
[tex]slope=-\frac{3}{5}[/tex]
The two lines have the same slope therefore they are not perpendicular but instead parallel to each other.
There are 35 boys in 6th grade. The number of girls in 6th grade is 40. Emma says that means the ratio of the number of boys in 6th grade to the number of girls in 6th grade is 3:4. Is Emma correct? If not, what is the correct answer?theses are the answers you chose froma: correct ratiob:7:8c: 5;8d: 8:7
Answer:
No, Emma is not correct.
Step-by-step explanation:
because if we put 35 and 42 in rational form we can write it to its simple form by dividing it
35 / 7 = 5
42 / 7 = 6
after dividing we get the answer as 5:6.

what is the value of c such that the line y=2x+3 is tangent to the parabola y=cx^2
The value of [tex]c[/tex] such that the line [tex]y = 2\cdot x + 3[/tex] is tangent to the parabola [tex]y = c\cdot x^{2}[/tex] is [tex]-\frac{1}{3}[/tex].
If [tex]y = 2\cdot x + 3[/tex] is a line tangent to the parabola [tex]y = c\cdot x^{2}[/tex], then we must observe the following condition, that is, the slope of the line is equal to the first derivative of the parabola:
[tex]2\cdot c \cdot x = 2[/tex] (1)
Then, we have the following system of equations:
[tex]y = 2\cdot x + 3[/tex] (1)
[tex]y = c\cdot x^{2}[/tex] (2)
[tex]c\cdot x = 1[/tex] (3)
Whose solution is shown below:
By (3):
[tex]c =\frac{1}{x}[/tex]
(3) in (2):
[tex]y = x[/tex] (4)
(4) in (1):
[tex]y = -3[/tex]
[tex]x = -3[/tex]
[tex]c = -\frac{1}{3}[/tex]
The value of [tex]c[/tex] such that the line [tex]y = 2\cdot x + 3[/tex] is tangent to the parabola [tex]y = c\cdot x^{2}[/tex] is [tex]-\frac{1}{3}[/tex].

What is the equation of the linear model in point-slope form that includes the point (-3, 1) and has a slope of 3?
Please show work for brainliest
Answer:
A) You would use the two points that are closest to the graphed line
(2,7) and (8,13)
B) Slope = change in Y over the change in X:
Slope = (13-7) / (8-2) = 6/6 = 1
Slope = 1
c) Point slope is written as y -y1 = m(x-x1) where m is the slope y1 is the first Y value and x1 is the first x value.
Equation is: y-7 = x-2
d) To rewrite y -7 = x-2 in slope intercept form, you need to isolate y.
To isolate Y add 7 to both sides:
y = x +5
Step-by-step explanation:
The equation of line which passes through point (-7,-2) and having slope 3 is y = 3x + 10.
What is Algebraic expression ?
Algebraic expressions are numbers expressed using letters or alphabets without specifying their values. Algebra taught us how to express unknown values using letters such as x, y, and z. There can also be a single value that is placed before and multiplied by a variable in an algebraic expression in addition to these letters, which are called variables.
Here, it is given that line passes though point (-3,1) and having slope of 3.
Now, Let us find the equation of the line using point-slope equation of line :
(y-y₁) = m(x-x₁)
Substituting all the values in above equation to get the equation of line :
(y-1) = 3(x-(-3))
y -1 = 3x + 9
y = 3x + 9 + 1
y = 3x + 10
Therefore, the equation of line which passes through point (-7,-2) and having slope 3 is y = 3x + 10.

what is the GCM of 9 and 7
Answer: See explanation
Step-by-step explanation:
Do you mean the greatest common factor (GCF), or the lowest common multiple (LCM).
If you mean GCF, then it is 1 because 7 is a prime number and has two facotrs (1 and itself) and since 9 isn’t divisible by 7, the GCF must be 1.
If you mean the LCM, the answer is 63. Using prime factorisation, we find the lowest prime factor of both numbers:
9 = 3^3
7= 7^1
Then, we multiply these together to give 63.
You cannot have a GCM, because you can’t find a greatest common multiple as numbers go on forever.

3x - 2y = 8
2x + 2y = -8
Answer:
(0, - 4 )
Step-by-step explanation:
3x - 2y = 8 → (1)
2x + 2y = - 8 → (2)
Adding (1) and (2) term by term will eliminate the y- term
5x + 0 = 0
5x = 0 , then
x = 0
Substitute x = 0 into either of the 2 equations and solve for y
Substituting into (2)
2(0) + 2y = - 8
0 + 2y = - 8
2y = - 8 ( divide both sides by 2 )
y = - 4
solution is (0, - 4 )
