Question

Convert the polar equation to rectangular form.  $r = - 9 \sec \theta$ 
A) $y = - 9$
B) $9 x = r$
C) $x = 9$
D) $y = 9$
E) $x = - 9$

Quizplus · Accepted Answer

The polar equation $r = -9 \sec \theta$ can be rewritten using the identity $\sec \theta = \frac{r}{x}$, leading to $r = -9 \frac{r}{x}$. Solving for $x$, we get $x = -9$.
