Students write and interpret a linear equation and an inequality with two variables and use the Inequality Graphing Application to map inequalities on a coordinate plane.

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

Distribute the pages to the class.

Follow the Activity procedures:

• Assign x to represent the number of 2-point field goals scored and y to represent the number of 3-point field goals scored
• Write a linear equation for the problem with two variables
• Rewrite the equation in slope-intercept form
• Graph the equation
• Record the ordered pairs that are possible solutions of the equation
• Rewrite the equation as an inequality (with the new condition)
• Use the Inequality Graphing application to graph the inequality
• Verify algebraically whether the points in the shaded region satisfy the inequality

Students will complete the Student Worksheet and answer questions.

Review student results:

• As a class, discuss questions that appeared to be more challenging
• Re-teach concepts as necessary
