An important calculation in calculus is the evaluation of the expression $$\frac { f ( x + h ) - f ( x ) } { h } , \text { where } h \neq 0 \text {. Find } \frac { f ( x + h ) - f ( x ) } { h }$$
-$$f ( x ) = - 14 - 5 x$$
A) $\frac { - 5 h - 28 } { h }$
B) $\frac { 5 h - 28 } { h }$
C) 5
D) $- 5$

The expression $\frac { f ( x + h ) - f ( x ) } { h }$ simplifies to $-5$, as the $h$ terms cancel out and the constant term does not depend on $h$.
