Plot each of the following points given in polar coordinates. Express the point in the other three equivalent ways. Then state the coordinates of the point in rectangular form.

$(-3,\frac{7\pi}{4})$
Hint (a):
From the pole (origin), move $3$ units left. Then rotate $7π/4$ units counterclockwise.

$(-2,-\frac{5\pi}{6})$
Hint (b):
From the pole (origin), move $2$ units left. Then rotate $5π/6$ units clockwise.
