Answer
Refer to the graph below.
Work Step by Step
Plot the point $(-\frac{5}{2}, 3)$.
Use the slope to plot another point.
A line with an undefined slope is vertical.
All points on a vertical line share the same x-coordinate.
Since $(-\frac{5}{2}, 3)$ is on the line, then the point $(-\frac{5}{2}, -3)$ must also be on the line. Plot $(-\frac{5}{2}, -3)$.
Complete the graph by using a line to connect the two points.
(Refer to the graph in the answer part above.)
