line l contains points (-2,4) and (1,-9). Point P has coordinates (14,-6) answer
We are given a line and a point, I assume that we want to see if the point is on the line or not.
We will see that the point does not belong to the line.
First, let's find the equation of the line.
A general line can be written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
If the line passes through points (x₁, y₁) and (x₂, y₂), then the slope can be computed as:
[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Here we know that our line passes through the points (-2, 4) and (1, -9). Then the slope is:
[tex]a = \frac{4 - (-9)}{-2 - 1} = \frac{13}{-3} = -\frac{13}{3}[/tex]
Then our line is something like:
[tex]y = -\frac{13}{3} *x + b[/tex]
To find the value of b, we can use one of the two points that we know that are on the line.
For example, the point (-2, 4) means that when x = -2, we must have y = 4.
Replacing that in the equation we get:
[tex]4 = -\frac{13}{3} *(-2) + b\\\\4 = \frac{26}{3} + b\\\\4 - \frac{26}{3} = b\\\\\frac{-14}{3} = b[/tex]
Now we can write the line equation as:
[tex]y = -\frac{13}{3} *x - \frac{14}{3}[/tex]
Now we need to see if the point (14, -6) belongs to the line.
To see this, we evaluate the line in x = 14.
[tex]y = -\frac{13}{3} *14 - \frac{14}{3} = -\frac{196}{3}[/tex]
This is different than -6, so the point does not belong to the line.

A proportional relationship goes through the point (4, 10). Explain how to write a function in the form y = mx for this relationship.
Answer:
m = 5 / 2
Step-by-step explanation:
Given
(4, 10)
Here,
x=4 and y=10
Given equation,
y=mx _ equation 1
putting the value of x and y in equation 1. we get,
y = mx
or, 10 = m4
or, 10 / 4 = m
or, 5 / 2 = m
therefore, m = 5 / 2

Round 6,248 to the nearest hundred
Answer:6200
Step-by-step explanation:
:We round the number up to the nearest hundred if the last two digits in the number are 50 or above.
: We round the number down to the nearest hundred if the last two digits in the number are 49 or below.
: If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.
:In this case, Rule B applies and 6248 rounded to the nearest hundred is:

In a particular year, a total of 49,652 students studied in two of the most popular host countries when traveling abroad. If 6786 more students studied in the most popular host country than in the second most popular host country,find how many students studied abroad in each country
How many students studied abroad in the most popular host country
x = most popular
y = second most popular
x+y=49652
x=y+6786
Substitute into the first equation
(y+6786)+y=49652
2y=49652-6786
2y=42866
y=21433
x=21433+6786=28219(answer)

What is the = to 5x+ 7 =42 please give details
Answer: x = 7
Step-by-step explanation:
5x + 7 = 42
We then take 7 away from both sides:
5x = 35
Then, we need to make it so x = answer. To make 5x into x, we divide by 5 meaning that we next need to divide both sides by 5.
x = 7

What is the slope of the line whose equation is 2x+3y = -12?
Answer:
slope = - [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
2x + 3y = - 12 ( subtract 2x from both sides )
3y = - 2x - 12 ( divide all terms by 3 )
y = - [tex]\frac{2}{3}[/tex] x - 4 ← in slope- intercept form
with slope m = - [tex]\frac{2}{3}[/tex]

What is the rate of change for the equation y = 2x + 100?
+
The rate of change is
h
Answer:
Rate of change = 2
Step-by-step explanation:
The rate of change is equivalent to the slope of the line !
A line is written:
y=mx+b
"m" is the slope, and "b" is the y-intercept !
The line you gave was "y=2x+100"
The slope, or "m," in your equation, would be 2 !
