Any line perpendicular to the

-axis is a vertical line. Vertical lines have the property that the

-coordinates of ALL points on the line are equal. Therefore, an equation of a vertical line has the form

where

is the value of the

-coordinate of any point on the line. Since you are given a point where the

-coordinate is equal to 4, then all the other points on the line must have an

-coordinate equal to 4.
