Answer
Refer to the graph below.
Work Step by Step
The graph of an equation of the form $x=h$ is a vertical line whose x-intercept is $(h, 0)$.
Each point on the line has an x-coordinate of $h$.
Thus, the graph of $x=3$ is a vertical line whose x-intercept is $(3, 0)$.
Each point on the line has an x-coordinate of $3$.
This, means that the following points are all on the line:
$(3, -2)$, $(3, 0)$, and $(3, 2)$
Plot the three points listed above then connect them using a line to complete the
graph. (refer to the attached image in the answer part above for the graph)
