-$( - 2,0 )$
A) $\left( 2,180 ^ { \circ } \right)$
B) $\left( 2,270 ^ { \circ } \right)$
C) $\left( - 2,180 ^ { \circ } \right)$
D) $\left( 2,90 ^ { \circ } \right)$

Quizplus · Accepted Answer

The point $(-2,0)$ in rectangular coordinates corresponds to a point 2 units to the left of the origin on the x-axis. In polar coordinates, this is represented as a radius $r = 2$ with an angle $\theta = 180^\circ$, indicating the direction directly to the left (or west) on the standard polar grid.
