Full solution stays hidden until you ask for it.
1. Subtract the y-values to find output change.
2. Subtract the x-values in the same order to find input change.
3. Divide output change by input change.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Subtracting x-values over y-values instead of output change over input change.
