Question

How do you graph the point `C(-3,-120^o)`?

Answer 1

The key is this point is going to be reflected through the origin to the other side of your polar plane.

Explanation:

First, the negative angle indicates your are going to measure it counterclockwise instead of clockwise, so this will put you in Quadrant 3.

Then, the negative magnitude indicates you reflect through the origin to the point 3 radius units away on the other side of your polar graph.
