You can put this solution on YOUR website! Tom was given this function table to complete.
X: -3, -2, -1, 0, 1, 2, 3
Y: -2, 0, 2, 4, 6, 8, 10
What is the rule of this function?

Notice that y increases by 2 when x increases by 1:
That is the slope
-----
Notice that f(0) = 4
That is the y-intercept.

Equation:
y = 2x +4
