Multiple Choice

Find the standard-form equation of the hyperbola centered at the origin which satisfies the given conditions.
-Asymptotes $y = \frac { 6 } { 7 } x , y = - \frac { 6 } { 7 } x$ ; one vertex is $( 7,0 )$

A) $\frac { x ^ { 2 } } { 49 } - \frac { y ^ { 2 } } { 36 } = 7$
B) $\frac { x ^ { 2 } } { 49 } - \frac { y ^ { 2 } } { 36 } = 1$
C) $\frac { y ^ { 2 } } { 49 } - \frac { x ^ { 2 } } { 36 } = 1$
D) $\frac { x ^ { 2 } } { 49 } - \frac { y ^ { 2 } } { 36 } = 1764$
