Calculus is a useful tool for describing and understanding rates of change and linear equations are a good place to begin the study of rates of change. In this module you will use the TI-83 to graph linear equations. You will also create scatter plots of real-world data, find linear regression equations that model sets of data, and explore what the slope of a linear equation tells you about the associated data's rate of change.

After completing this module, you should be able to do the following:

• Find linear equations and graph equations on the TI-83
• Use the Zoom Standard, Zoom Square and Trace features of the TI-83
• Create scatter plots from data sets
• Find linear regression equation models to fit data sets
• Explain what the slope of the linear regression equation tells you about the data
