Walkthrough shown
Full solution stays hidden until you ask for it.
1. Read the two endpoint coordinates.
2. Compute change in y divided by change in x.
3. Interpret the secant slope over the interval.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Using a tangent slope at one endpoint.
