Answer:
y = 4x+23
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = 4x+b
Substitute the point into the equation
7 = 4(-4)+b
7 = -16+b
Add 16 to each side
7+16 = b
23 = b
y = 4x+23
Find the slope of the line passing throught the points (2, 2) and (4, 3).
The formula of a slope:
![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Substitute:
![m=\dfrac{3-2}{4-2}=\dfrac{1}{2}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B3-2%7D%7B4-2%7D%3D%5Cdfrac%7B1%7D%7B2%7D)
If the point (x, -1) lie on the same line, then the slope of line passing through the points (2, 2) and (x, -1) the same:
Substitute:
![m=\dfrac{-1-2}{x-2}=\dfrac{-3}{x-2}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B-1-2%7D%7Bx-2%7D%3D%5Cdfrac%7B-3%7D%7Bx-2%7D)
We have the equation:
<em>cross multiply</em>
![(1)(x-2)=(-3)(2)](https://tex.z-dn.net/?f=%281%29%28x-2%29%3D%28-3%29%282%29)
<em>add 2 to both sides</em>
![x=-4](https://tex.z-dn.net/?f=x%3D-4)
