9-114.

For each of the rectangular coordinates pairs below, write two equivalent polar coordinate pairs.

1. $(3,−3)$

Graph each point and draw a segment connecting the point to the origin. Create a right triangle to determine the length and direction of the segment.

Recall that each point can be written four ways: $(+, +), (+, –), (–, –),$$\text{ and } (–, +)$

1. $(0,0)$

It the radius is $0$, does it matter what the angle is?

1. $(0,−5)$

1. $\left(−2,2\sqrt{3}\right)$
