Find the missing endpoint value given average rate of change: average rate from x=1 to x=4 is -2 and f(1)=10.
Using a hint is okay. It just tells the trainer to give you a little more review.

Walkthrough
Full solution stays hidden until you ask for it.
1. Use average rate = (f(b)-f(a))/(b-a).
2. Substitute known values.
3. Solve for the missing endpoint value.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Using rate as total change without multiplying by interval length.
