SOLUTION
Consider the given coordinates
[tex](-3,-\frac{7\pi}{4})[/tex]
Since the angle given is negative, we move in the clockwise direction
Henece
[tex]\frac{7\pi}{4}=\frac{7\pi}{4}\times\frac{180}{\pi}=315^0[/tex]
Moving in the clockwise direction, the angle 315 falls in the first quadrant.
Then, -3 will be to move to the third quadrant,
hence the right option will be
