#### Answer

Refer to the graph below.

#### Work Step by Step

Solve for $y$:
$y+2=0
\\y+2-2=0-2
\\y=-2$
This means the given equation is equivalent to $y=-2$.
RECALL:
The graph of the equation $y=k$ is a horizontal line whose y-intercept is $(0, k)$.
Every point on the line has a y-coordinate of $k$.
Thus, the graph of the equation $y=-2$ is a horizontal line and every point on the line has a y-coordinate of $-2$.
This means the following points are on the line: $(-3, -2)$ and $(3. -2)$.
Plot the two points above and connect them using a straight line.
