Solving Systems of Linear Equations by Graphing

Published on 04/15/2009

Activity Overview

The mathematics goal of this activity is to deepen students' understanding of solving systems of linear equations by graphing.

At the end of a 90 minutes class, students should be able to:

  1. Graph the two given equations simultaneously using the TI-Nspire graphing calculator;
  2. Give the coordinates of the point of intersection;
  3. Solve real world problems by applying the concept of solving systems of linear equations by graphing;
  4. Complete the group activity collaboratively.

Before the Activity

Load VideoRental3.tns file onto all the students' handhelds. The activity consists of a problem designed to be teacher directed with time for students to investigate and record their observations.

During the Activity

See directions in the attached teacher document.
