Multiple Choice

Graph the Polar Equations of Conics
- $r = \frac { 9 } { 3 - \sin \theta } \quad$ Identify the directrix and vertices.

• A) directrix: 9 unit(s) below the pole at \(x = 9\) the pole at \(\mathrm { y } = - 9\) vertices: \(\left( \frac { 9 } { 2 } , \frac { \pi } { 2 } \right) , \left( \frac { 9 } { 4 } , \frac { 3 \pi } { 2 } \right)\)
• B) directrix: 9 unit(s) to the right of vertices: \(\left( \frac { 9 } { 2 } , \pi \right) , \left( \frac { 9 } { 4 } , 0 \right)\)
• C) directrix: 9 unit(s) to the left ofthe pole at \(x = - 9\) vertices: \(\left( \frac { 9 } { 4 } , \pi \right) , \left( \frac { 9 } { 2 } , 0 \right)\)
• D) directrix: 9 unit(s) above the pole at \(\mathrm { y } = 9\) vertices: \(\left( - \frac { 9 } { 4 } , \frac { 3 \pi } { 2 } \right) , \left( \frac { 9 } { 2 } , \frac { 3 \pi } { 2 } \right)\)
