Full solution stays hidden until you ask for it.
1. Compute the rate over each interval.
2. Compare the rates.
3. A linear table must have one constant rate, so changing rates show it is not linear.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Saying not linear only because points are not in a simple counting pattern.
