Answer:

x = 2

Explanation:

y = 4 is a horizontal line parallel to the x- axis.

A line perpendicular to it will be vertical and parallel to the y- axis with equation

x = c ( where c is the value of the x- coordinates the line passes through )

The line passes through (2, - 7 ) with x- coordinate 2 , then

x = 2 ← equation of perpendicular line
