• A) \(\frac { x ^ { 2 } } { 9 } - \frac { y ^ { 2 } } { 81 } = 1\)
• B) \(\frac { x ^ { 2 } } { 9 } + \frac { y ^ { 2 } } { 81 } = 1\)
• C) \(\frac { x ^ { 2 } } { 81 } + \frac { y ^ { 2 } } { 9 } = 1\)
• D) \(\frac { x ^ { 2 } } { 81 } + \frac { y ^ { 2 } } { 72 } = 1\)
• E) \(\frac { x ^ { 2 } } { 72 } + \frac { y ^ { 2 } } { 81 } = 1\)
