Unformatted text preview: of a graph is a good start. But the best way to find out whether the data are relatively linear is to analyze the rate of change between the variables in tables. If the ratio of the change in the yvalues to the change in the xvalues is relatively constant, then a linear model is appropriate. Creating models for data is an important theme in mathematics. What you have learned about creating linear models in this topic forms a basis for creating models of nonlinear data. You will learn how to create models for nonlinear data in future topics in this algebra course, as well as in your other mathematics courses....
