Change in the dependent variable Change in the independent variable Rate of Change Rate of Change = _________________________________________ Find the rate of change using a table. Cost of Renting a Computer 1. Computer Usage A. For the data in the table, is the rate of change for each pair of consecutive days the same? Hint: Identify the independent and dependent variables first! Rate of change = ________________________ B. Find the rate of change using days 5 and 2. C. Does finding the rate of change for just one pair of days mean that the rate of change is the same for all the data? Explain. D. What does the rate of change represent? Rate of change = ________________________ allows you to see the relationship between two quantities that are changing. If one quantity depends on the other, then the following is true. Change in the dependent variable Change in the independent variable We can create a graph of the data and see (or find) the rate of change. Remember: the independent variable is plotted on the ___________ axis the dependent variable is plotted on the ____________ axis.

Find the rate of change using a graph. 2. Airplane Altitude. The graph shows the altitude of an airplane as it comes in for a landing. A. Find the rate of change. B. Explain what this rate of change means. 3. Moving Automobile. Find the rate of change of the data in the graph.
