How Many Drivers? Investigate the Slope-Intercept Form of a Line

Published on

Activity Overview

In this activity, students will be introduced to the slope-intercept form of a linear equation. They will recognize the effects of changes in the slope and y-intercept on the graph of a line. Students will use the Transformation Graphing application to find an approximate linear model of the actual data. They will determine the line of best fit on a scatter plot by using the guess-and-check strategy to manipulate the values of the slope and y-intercept.

Before the Activity

Install the Transformation Graphing application on the students' graphing calculators using one of these two methods:

TI-Connect™, a TI Connectivity Cable, and the Unit-to-Unit Link Cable
