Determine the Two Equations Necessary to Graph the Horizontal Parabola $$x = 8 y ^ { 2 } - 5 y + 7$$

Determine the two equations necessary to graph the horizontal parabola using a graphing calculator.
- $$x = 8 y ^ { 2 } - 5 y + 7$$

A) $\mathrm { y } = \frac { 5 - \sqrt { 32 \mathrm { x } - 199 } } { 16 }$ and $\mathrm { y } = \frac { 5 + \sqrt { 32 \mathrm { x } - 199 } } { 16 }$
B) $y = \sqrt { \frac { x - 7 } { - 5 } }$ and $y = - \sqrt { \frac { x - 7 } { - 5 } }$
C) $\mathrm { y } = \frac { 5 - \sqrt { 32 \mathrm { x } - 199 } } { 8 }$ and $\mathrm { y } = - \frac { 5 + \sqrt { 32 \mathrm { x } - 199 } } { 8 }$
D) $y = \frac { \sqrt { x - 7 } } { - 5 }$ and $y = - \frac { \sqrt { x - 7 } } { - 5 }$
