Question

Find anequation for the vertical line through the point (-5, -3).

Answer 1

A line is vertical, then all points lie on it have the same x-coordinates

If line L is a vertical line and passes through the point (a, b), then its equation is

$x=a$

Since the given line is a vertical line and passes through the point (-5, -3)

That means a = -5

Then its equation is

$x=-5$
