Quizplus · Accepted Answer

The polar coordinates of a point are given by $(r, \theta)$, where $r$ is the distance from the origin to the point, and $\theta$ is the angle formed with the positive x-axis. For the point $(-3,0)$, $r = 3$ (distance from origin) and $\theta = \pi$ (180 degrees) because the point is on the negative x-axis.
