## The Variables of Renting #### Activity Overview

In this activity, students will identify what a variable is, construct a table of values, graph the ordered pairs from the table, and use the TI-84 Plus C Silver Edition to graph the equation.

#### Key Steps

• Students will identify what a variable is, construct a table of values, graph the ordered pairs from the table, and use the TI-84 Plus C Silver Edition to graph the function. First, students look at the video rental rates using number sentences.

• Then, students graph the scatter plot of ordered pairs and look at the line that passes through all the points.

• Finally, students analyze the table of function values generated from function representing the video rental scenario.
