Answer: x = -5 (rewritten: x + 5 = 0)

Explanation:

First, we must take into account that the line is parallel to the y-axis. If a line is parallel to the y-axis, it is vertical, meaning that for every y-value, there can only be one x-value. Since the question contains a point that the line passes through, which is (-5, 2), we know that for every y-value of the line, the x-value will always equal -5. Thus, the equation of the line must be x = -5 (or, rewritten, x + 5 = 0).
