We will be using the Point Slope formula which is 
The information we are given is that m = -4 and the point is (2,-5), so we can input it into the equation.

This simplifies into 
Then we can subtract 5 from each side to get the answer:

It is 5! you do 35 divided by 5 it is 7
The answer is the second choice.
(4,4) is a solution to both line A and B
The length is 37in. The width is 7in.
