1. Problem Description

The problem asks for the equation of a vertical line that passes through the point (−1,−2)(-1, -2).

2. Solution Steps

A vertical line has the equation x=cx = c, where cc is a constant. Since the line passes through the point (−1,−2)(-1, -2), the x-coordinate of this point must satisfy the equation of the line. Therefore, c=−1c = -1, and the equation of the vertical line is x=−1x = -1.

3. Final Answer

The equation of the vertical line is x=−1x = -1.
The answer is (A).
