Answer:
y = 2
Step-by-step explanation:
x = - 3 is the equation of a vertical line parallel to the y- axis.
Thus a perpendicular line must be a horizontal line parallel to the x- axis with equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (- 4, 2) with y- coordinate 2, thus
y = 2 ← equation of perpendicular line
