Answer
Refer to the graph
Work Step by Step
RECALL:
The graph of an equation in the form $y=k$ is a horizontal line whose y-intercept is $(0, k)$ and is parallel to the x-axis. All points of the line have a y-intercept of $k$.
Thus, the graph of the equation $y=-2$ is a horizontal line whose y-intercept is $(0, -2)$. All points on the line have a y-coordinate of $-2$.
This means that points $(2, -2)$, $(0, -2)$, and $(-2, -2)$ are all on the line $y=-2$.
Plot these three points then connect them using a line.
