Question

Which equation represents a line which is perpendicular to the x-axis?

Answer 1

Y= 4 is perpendicular to the x- axis

The x- axis is the horizontal line, and the y- axis is the vertical line

Answer 2

The equation that represents a line which is perpendicular to the x-axis is: x = 4

How to find the equation of the Line?

The general formula for the equation of a Line in slope intercept form is:

y = mx + c

where:

m is slope

c is y-intercept

A line that is perpendicular to the x-axis will have the equation starting with x before the equal to sign.

The only option showing that condition is x = 4
