Prove that the graphs of the equations 3x–y=–5 and –x+10y=21 and 11x+21y=31 intersect at the point P (–1, 2).

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
