Answer:
x = - 4
Step-by-step explanation:
y = - 8 is the equation of a horizontal line parallel to the x- axis.
A perpendicular line must then be a vertical line parallel to the y- axis.
The equation of a vertical line is x = c
where c is the value of the x- coordinates it passes through.
The line passes through (- 4, - 2) with x- coordinate - 4, thus
x = - 4 ← equation of perpendicular line
