Work Step by Step

The graph of an equation in the form $y=k$ is a horizontal line whose y-intercept is $(0, k)$. All points on this line have a y-coordinate of $k$. This means that the following points are on the line $y=-2$: $(2, -2)$, $(0, -2)$, and $(-2, -2)$. Plot the three points above then connect them using a line. (Refer to the graph in the answer part above.)
