Answer

Refer to the image below for the graph.
1503150887

Work Step by Step

Divide 7 on both sides of the equation to obtain: $y=-\frac{21}{7}$ $\\y=-3$ RECALL: The graph of an equation of the form $y=k$ is a horizontal line whose y-intercept is $k$. The given equation has $k=-3$ therefore its graph is a horizontal line whose y-intercept is $-3$. The points on the line share the same y-value of $-3$. This means that the line contains the points $(-2, -3)$, $(0, -3)$, and $(2, -3)$. To graph $y=-3$, plot the three points then connect them using a line. (refer to the attached image in the answer part for the graph)
