What quadrant is (8 1/2,-4) located in

The coordinates of a, b, and c in the diagram are a(p,4), b(6,1), and c(9,q). which equation correctly relates p and q? hint: since is perpendicular to , the slope of × the slope of = -1. a. p - q = 7 b. q - p = 7 c. -q - p = 7 d. p + q = 7

Negative 5 1/12 + negative 4 1/4 + 6 3/4

Another type of subtraction equation is 16-b=7. explain how you would sole this equation then solve it.
