Write an Equation of the Line $y = - \frac { 8 } { 7 } x + 39$

Write an equation of the line. Write the equation in the form x = a, y = b, or y = mx + b.
-Through (9, -12) ; parallel to 7x + 8y = 39

A) $y = - \frac { 8 } { 7 } x + 39$
B) $y = - \frac { 8 } { 7 } x - 12$
C) $y = \frac { 7 } { 8 } x - \frac { 33 } { 8 }$
D) $y = - \frac { 7 } { 8 } x - \frac { 33 } { 8 }$
