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.
