Find an equivalent equation in polar coordinates.
-$$y = x$$
A) $\sin \theta = - \cos \theta$
B) $r = \sin \theta$
C) $\mathrm { r } = \cos \theta$
D) $\sin \theta = \cos \theta$

Quizplus · Accepted Answer

The equation $y = x$ in Cartesian coordinates translates to $r\sin\theta = r\cos\theta$ in polar coordinates. Dividing both sides by $r$ (assuming $r \neq 0$) gives $\sin\theta = \cos\theta$, which matches option D.
