Graph the Polar Equations of Conics
- $r = \frac { 2 } { 2 - 2 \cos \theta } \quad$ Identify the directrix and vertex.

A) directrix: 1 unit(s) to the left of
the pole at $x = - 1$
vertex: $\left( \frac { 1 } { 2 } , \pi \right)$

B) directrix: 1 unit(s) to the right of
the pole at $x = 1$
vertex: $\left( \frac { 1 } { 2 } , 0 \right)$

C) directrix: 1 unit(s) above
the pole at $\mathrm { y } = 1$
vertex: $\left( \frac { 1 } { 2 } , \frac { \pi } { 2 } \right)$

D) directrix: 1 unit(s) below
the pole at $\mathrm { y } = - 1$
vertex: $\left( \frac { 1 } { 2 } , \frac { 3 \pi } { 2 } \right)$
