Question

The graph of the line through (2,3) that is perpendicular to the line with equation X=-1 also goes through which point?

Answer 1

x = -1.....this is a vertical line where x is always gonna be -1. A perpendicular line to a vertical line is a horizontal line. A horizontal line is represented by y = a number.
(2,3)......here, y = 3....so another set of points is (0,3)
