Answer:
y = - 2
Step-by-step explanation:
x = - 6 is the equation of a vertical line parallel to the y- axis.
A line perpendicular to it is 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 (- 1, - 2) with y- coordinate - 2, thus
y = - 2 ← equation of perpendicular line
