Work Step by Step

To plot the point $(r, \theta )=(-2, -\frac{\pi }{2} )$, begin with the $-\frac{\pi }{2}$ angle. Because $-\frac{\pi }{2}$ is a negative angle, draw $\theta = -\frac{\pi }{2}$ clockwise from the polar axis. Now consider $r=-2$. Because $r \lt 0$, plot the point by going out two units along the ray opposite the terminal side of $\theta$.
