Problem 25 of 7
Estimate the average rate of change from graph endpoint estimates (1,2) and (5,10).
Hints
Using a hint is okay. It just tells the trainer to give you a little more review.

Full solution stays hidden until you ask for it.
1. Read or estimate endpoint coordinates from the graph.
2. Compute approximate change in y over change in x.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Using only vertical change without dividing by horizontal change.
