You can put this solution on YOUR website! Take a look at the table below and write out an equation for f(x).
x::: -2 -1 0 1 2
f(x) -2 2 6 10 14
---------------------------
As x increases 1, f(x) increases 4; so the slope is 4
----------------
f(0) = 6, so the intercept is 6
-----------------
Therefore the equation is f(x) = 4x+6
