Multiple Choice

An equation that defines y as a function of x is given. Solve for y in terms of x, and replace y with the function notation
f(x) .
- $$5 x + 9 y = 19$$

A) $f ( x ) = 5 x - 19$
B) $f ( x ) = - \frac { 5 } { 9 } x + \frac { 19 } { 9 }$
C) $f ( x ) = \frac { 5 } { 9 } x - \frac { 19 } { 9 }$
D) $f ( x ) = \frac { 5 } { 9 } x + \frac { 19 } { 9 }$
