First, use the points to find the equation of JK:
Given that JK passes through (4,5) and (144,75) we can find the slope as follows:
Slope is found via:
Plug in and calculate:
Next, we need to use one of our points and the slope to find our y-intercept. I'll use (4,5).
So our answer is:
To find y, we need to plug in 16 for x and solve:

One way to solve this one is by plugging in each of the answer choices and eliminating any that don't work out. Begin with our original g(x)
If we plug in 3 we get
,
So our point is (3,28).
