Answer
Refer to the graph below.
Work Step by Step
Divide both sides of the equation by $12$:
$\dfrac{12y}{12}=\dfrac{-360}{12}
\\y=-30$
This means that the given equation is equivalent to $y=-30$.
Recall that 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 $12y=-360$, which is the same as the graph of $y=-30$, is a horizontal line whose y-intercept is $(0, -30)$.
Each point on the line has a y-coordinate of $-30$.
This means that the following points are all on the line:
$(8,-30), (0,-30), \text{ and } (-8,-30)$
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.)
