Answer

Refer to the graph below.

Work Step by Step

RECALL: The graph of an equation in the form $x=h$ is a vertical line whose x-intercept is $(h, k)$ and is parallel to the y-axis. All points of the line have an x-coordinate of $h$. Thus, the graph of the equation $x=1$ is a vertical line whose x-intercept is $(1, 0)$. All points on the line have an x-coordinate of $1$. This means that points $(1, -2)$, $(1, 0)$, and $(1, 2)$ are all on the line $x=1$. Plot these three points then connect them using a line. (refer to the attached image in the answer part above for the graph)
