Refer to the graph below.

Work Step by Step

RECALL: A line whose slope is $0$ is a horizontal line. Horizontal lines have equations of the form $y=k$ and have a y-intercept of $(0, k)$. All points on the line have a y-coordinate of $k$. Thus, the given line is a horizontal line, and all points on the line have a y-coordinate of $-5$. This means the following points are on the line: $(0, -5)$, $(2, -5)$, and $(-2, -5)$ Plot the three points above and connect them using a line to complete the graph. (Refer to the attached image above for the graph.)
