#### Answer

Refer to the graph below.

#### Work Step by Step

The graph of an equation of the form $y=k$ is a horizontal line whose y-intercept is $(0, k)$. Each point on the line has a y-coordinate of $k$. Thus, the graph of $y=0$ is a horizontal line whose y-intercept is $(0, 0)$. Each point on the line has a y-coordinate of $0$. This, means that the following points are all on the line: $(-2, 0)$, $(0, 0)$, and $(2, 0)$ 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)
