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:
plug in the x- and y- values of the two points above
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
