5. What is rate of change?
Rate of Change: the relationship between two quantities that are changing. THIS IS THE SAME AS SLOPE!

6. Finding rate of change using a table
The table shows the distance a band marches over time. Is the rate of change in distance with respect to time constant? What does the rate of change represent?

7. Let’s try again…
What happens if we try to find the rate of change and use nonconsecutive rows of the table? Explain.
