Step-by-step explanation:
The slope is 1/4 since y increases 1 when x increases by 4 (you divide deltaY by deltaX).
Then, to make it go through (0,-4) you subtract -4.

Answer:
8x-3
Step-by-step explanation:
The total perimeter is the length of all the sides of the triangle added together, in this case that is 11x+1. In order to get the length of the one side by itself subtract the other two side lengths from the perimeter. (11x+1)-(x+5)=10x-4. (10x-4)-(2x-1)=8x-3.
