The letters x and y represent rectangular coordinates. Write the equation using polar coordinates (r, θ).
-$$x = - 3$$
A) $r \cos \theta = - 3$
B) $\mathbf { r } \cos \theta = 3$
C) $r \sin \theta = - 3$
D) $r \sin \theta = 3$

Question

Quizplus · Accepted Answer

The equation $x = -3$ in rectangular coordinates can be converted to polar coordinates using the relation $x = r \cos \theta$. Therefore, $r \cos \theta = -3$ correctly represents the equation in polar coordinates.
