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 from the positive x-axis to the point. For the point $(-2, 0)$, $r = 2$ (distance from origin) and $\theta = 180^\circ$ (angle from positive x-axis, pointing directly left).
