Tracing Paper Inequalities

Activity Overview

Students graph systems of linear inequalities in two variables in the Cartesian coordinate plane and find their solutions.

Before the Activity

Install the Inequality Graphing Application on the calculator using one of these two methods:

TI Connect™, a TI Connectivity Cable, and the Unit-to-Unit Link Cable
TI-Navigator™ "send to class" feature

See the attached PDF file for detailed instructions for this activity
Print pages 17-22 from the attached PDF file for your class

During the Activity

Distribute the pages to your class.

Follow the Activity procedures:

Write down two linear inequalities with 2 variables and graph them on sketch papers

Place the two graphs one on top of the other and align the axes

Observe the common shaded region

Verify these graphs by using the Inequality Graphing Application

Verify algebraically whether a point is a part of the solution set

Observe that a system of linear inequalities has a common region as a solution set, whereas a system of linear equations has only one solution, the point of intersection

After the Activity

Students will complete the Student Worksheet and answer questions listed in it.

Review student results:

As a class, discuss questions that appeared to be more challenging

Re-teach concepts as necessary
