Question 743702
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
