Question

Write the equation of a vertical line that passes through the point (–4, 4).

A) y = 4
B) y = – 4
C) x = – 4
D) x = 4

Answer 1

The question asks for a vertical line, and if it is vertical, it cannot be y = ... because that is horizontal. We also know it passes through the x-coordinate of -4, so the answer is x = -4.
