-$\left( - 9 , - \frac { \pi } { 3 } \right)$
A) $\left( - \frac { 9 } { 2 } , \frac { - 9 \sqrt { 3 } } { 2 } \right)$
B) $\left( \frac { 9 } { 2 } , \frac { 9 \sqrt { 3 } } { 2 } \right)$
C) $\left( - \frac { 9 } { 2 } , \frac { 9 \sqrt { 3 } } { 2 } \right)$
D) $\left( \frac { 9 } { 2 } , \frac { - 9 \sqrt { 3 } } { 2 } \right)$

Quizplus · Accepted Answer

The point is in the third quadrant, so the x-coordinate is negative and the y-coordinate is positive. The distance from the origin to the point is 9, so the x-coordinate is -9/2 and the y-coordinate is 9√3/2.
