Answer:


f(x)=3x-10

Explanation:

Recall point-slope form: Given a point
(x_(1), y_(1)) and the slope
m, the equation for the line is
y-y_(1)=m(x-x_(1)).

We can plug in for our point and slope!

The equation for the line is
y-14=3(x-8).

Distributing the right side gives
y-14=3x-24.

Adding
14 to both sides gives
y=3x-10.

So, the function is
\boxed{f(x)=3x-10} and we're done!
