Question

Find the equation of the line perpendicular to the given line and passing through the given point. y=−3; (3,−7)

Answer 1

x = 3

Explanation:

Given line y = -3, which means slope = 0 so y = -3 is parallel to the the x-axis. So the line that is perpendicular to x-axis is parallel to y-axis.

So the line parallel to y-axis passes through (3,-7) is x = 3
