when writing the equation of a line in slope-intercept form, how can you determine the value of m in y=mx+b if you know the coordinates of two points on the line?

Answers

To determine the value of m in the equation, apply the slope formula, m [tex]= \frac{y_2 - y_1}{x_2 - x_1}[/tex].

How to Determine the Slope of a Line?

The slope of a line (m) = change in y / change in x = (y2 - y1)/(x2 - x1).

In the slope-intercept form of an equation that represents a line, the slope is represented as "m" in y = mx + b.

The equation we can use to determine the slope (m) if we are given two points on a line is, m = (y2 - y1)/(x2 - x1).

For example, if two points, (-4,2) and (8,5) are points on the line, we can find the value of the slope (m) as:

m = (2 - 5)/(-4 - 8) = -3/-12

Slope (m) = 1/4

The value of m to use in the equation of the line would be 1/4.

Answer:

y= 3 when x= 0

y=3

Step-by-step explanation:

in the problem, there's a patten in the difference of X and Y,

at first, Y is 3 more than X (2 and 5)

then y is 4 more, 5 more, and 6 more.

y goes up by 1 each time

so if Y is 5 when X is 2, then when X is 1 Y is 4

when X is 0 Y is 3

Find the direct variation.

if y=28 when x= 168, find y when x =108.

Answers

Answer:

18

Step-by-step explanation:

168 : 28 : : 108 : y

168 / 28 = 108 / y

6 = 108 / y

6 * y = 108

y = 108 / 6

y = 18

Answer:

y = 18

Step-by-step explanation:

Given y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 28 when x = 168

28 = 168k ( divide both sides by 168 )

[tex]\frac{28}{168}[/tex] = k , that is

k = [tex]\frac{1}{6}[/tex]

y = [tex]\frac{1}{6}[/tex] x ← equation of variation

When x = 108 , then

y = [tex]\frac{1}{6}[/tex] × 108 = 18

Jamal's parents give him $20 to spend at camp . Jamal spends the same amount of money on snacks each day . After 4 days he has $12 left . What rate is Jamal spending money ? Calculate the slope using the formula

Answers

Step-by-step explanation:

20 - 12 = 8 so he spent 8$ in 4 days.

8 ÷ 4 = 2, so he spent 2$ each day

The rate of Jaman spending money every day will be $2.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Jamal's parents give him $20 to spend at camp. Jamal spends the same amount of money on snacks each day. After 4 days he has $12 left .

The rate of spending money every day will be calculated as,

Spending in 4 days, 20 - 12 =$8

Rate of spending  = 8 ÷ 4 = $2

Therefore, the rate of Jaman spending money every day will be $2.

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

Answer:

d.

Step-by-step explanation:

The answer to this question would be A. But why? First you see the point on (-2,3) and than it asks for you to rotate the point 90 degrees. Now, this is where things get tricky because it doesn’t specifically ask for any sort of rotation and in seeing this we assume they mean clock wise because they didn’t state otherwise. So after rotating the point 90 clockwise we land at the point (2,3). I hope this helps!
