Since 
is a linear function with slope 
,
![\[\frac{f(6) - f(2)}{\Delta x} = m\]](http://latex.artofproblemsolving.com/f/9/8/f98308f5aaeb340e004029bf311e31a1673ced75.png)
\[\frac{12}{\6 - 2} = m\] (Error compiling LaTeX. Unknown error_msg)
![\[m = 3\]](http://latex.artofproblemsolving.com/d/7/c/d7ca60caf7960f69346979efd814f84ee85b7f70.png)
$$ (Error compiling LaTeX. Unknown error_msg)f(12) - f(2) = m \Delta x = 4(12 - 2) = 30 \Rightarrow \text (D)
