You can put this solution on YOUR website! If f(4)=0 and f(6)=6, which of the following could represent f(x)?
You have two points: (4,0) and (6,6)
----
slope = (6-0)/(6-4) = 3
--------------------
Form is y = mx + b
You have m=3 and y = 0 when x = 4
Solve for "b":
--
0 = 3*4 + b
b = -12
------------------
Equation:
y = 3x -12
-----------------
