Answer:
y = -4x + 9
Step-by-step explanation:
using any two points, in this case (0, 5) and (3, -7) you can find slope by using this formula: ![m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D)
plug in the x- and y- values of the two points above
![m=\frac{-7-5}{3-0}=\frac{-12}{3}=-4](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-7-5%7D%7B3-0%7D%3D%5Cfrac%7B-12%7D%7B3%7D%3D-4)
y = -4x + b
use any point of the line and plug it into the equation above
5 = -4(0) + b
5 = -4 + b
5 + 4 = -4 + b +4
9 = b
the equation in full is y = -4x +9
The effect of doubling the length and width have on the perimeter would be 2x bigger
The answer is 19y – 9.
First, distribute the -3 to ( -4y + 3 ). So:
= ( 12y – 9 ) + 7y
Then, combine like terms. In this case, the like terms are 12y and 7y. So:
= 12y – 9 + 7y
= 19y – 9
6000 would be your answer
