#### Answer

Refer to the graph below.

#### Work Step by Step

RECALL:
The graph of an equation of the form $x=h$, where $h\ne0$, is a vertical line whose x-intercept is $(h, 0)$. All points on the line have an x-coordinate of $h$.
Thus, the graph of $x=3$ is a vertical line whose x-intercept is $(3, 0)$.
All points on the line have an x-coordinate of $3$ so the following points are on the line:
$(3, 2)$
$(3, 0)$
$(3, -2)$
Plot the three points then connect them using a line to complete the graph.
(Refer to the graph in the answer part above.)
