Use long multiplication to evaluate.

You reverse what you did, so first you go 5 units down which makes the coordinates (9,1) then you move 3 units left which then is (6,1). Then you go 4 units up which lets you end out at (6,5).
You would use the Pythagorean there on which is a^2+b^2=c^2, from there you plug int what they gave you and solve for b, and b=12
Slope intercept form y = -8x - 81
Point slope form (y - 7) = -8 (x + 11)
