## Linear Equations: Using Graphs and Tables

#### Activity Overview

Students learn to locate the real number solution of a linear equation using tables. They also learn to locate the real number solution of a linear equation using graphical method on a Cartesian (x-y) graph.

#### Before the Activity

Install Topics in Algebra 1 (Chapters 1-4) App on the calculator using one of these two methods:

• TI Connect&trade, 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 2-1 to 2-5 from the attached PDF file for your class
• #### During the Activity

Distribute the pages to the class.

• Use a table and a number line to find the solution to a linear equation
• Solve linear equations and pick the right answer from the given four options
• Use the table of values of equations and answer the questions
• Use the table feature on the calculator to find the solution to the question
• Estimate the solution to the given equation and record it
• Use the calculator and find the solution to the equation
• Use the graphing feature to graph the two equations
• Determine the point of intersection, and find the solution
• Record the answer and explain the solution
• Solve more problems using tables and graphs
• #### After the Activity

Students will complete the Student Worksheet and analyze the results.

Review student results:

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