Question

What is the equation of a vertical line passing through (−5, −2)?

x = −5
y = −2
x = −7
y = −3

Answer 1

A vertical line will pass through one value of x
here the equation is x = -5 ( the x coordinate of (-5,-2)

Answer 2

x = -5

First option is correct.

Explanation:

The vertical line is passing through the point (−5, −2).

The equation of a vertical line is in the form x = k

For vertical line, the x-coordinate of each point that lie on the line remains same. Only the y-coordinate is different

For the given point, the x-coordinate = -5

Hence, k = -5

Therefore, the equation of line is x = -5

First option is correct.
