Can someone tell me if I’m right?

What is the rate of change of a line that passes through (2,-5) and (6,-2)?

Pranza plotted point a in the coordinate plane below.

Write an equation of the line that passes through the point (2, 3) and is perpendicular to the line x = -1. a) y = 1 b) y = 3 c) y = 0 eliminate d) y = -3
