You are given 2 points on the graph of your linear function. At 2 the value of the function is 66. At 5 the value of the function is 150. Hence your points are and

Use the two-point form of an equation of a line:



where and are the coordinates of the given points.

Once you have written and simplified your equation, substitute 9 for and solve for
