• A) \[\frac { ( x + 2 ) ^ { 2 } } { \frac { 69 } { 8 } } + \frac { ( y + 9 ) ^ { 2 } } { \frac { 69 } { 8 } } = 1\] ;ellipse
• B) \(\frac { ( x + 2 ) ^ { 2 } } { \frac { 11 } { 8 } } + \frac { ( y + 9 ) ^ { 2 } } { \frac { 11 } { 8 } } = 1\) ;ellipse
• C) \(( 8 x + 2 ) ^ { 2 } + ( 8 y + 9 ) ^ { 2 } = 320\) ;circle
• D) \(( x + 2 ) ^ { 2 } + ( y + 9 ) ^ { 2 } = 40\) ;circle
• E) \(( x + 2 ) ^ { 2 } + ( y + 9 ) ^ { 2 } = 20\) ;circle
