Answer:

y = 8

Step-by-step explanation:

x = 4 is the equation of a vertical line parallel to the y- axis.

A perpendicular line will be a horizontal line with equation

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

the line passes through (- 9, 8 ) with y- coordinate 8 , then

y = 8 ← equation of perpendicular line
