Answer
$x=-3$
Work Step by Step
RECALL:
(i) Vertical lines have equations of the form $x=h$ where $h$ is a constant.
(ii) The vertical line $x=h$ contains the points $(h,y)$. where $y$ is any real number.
The given vertical line contains the point $(-3, 2)$, which means that $h=-3$.
Thus, the equation of the vertical line is $x=-3$.
