Need helps with the picture below

In the coordinate plan (-6,9) b (3,9) c (3,3) def is shown in the coordinate plan below

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

For the following geometric sequence, find the recursive formula. {-80, 20, -5, } i need : ')
