Introduction to Graphing Linear Equations on the TI83

A. Objectives:

This is an introduction to graphing calculators. These students have not used a

calculator to graph before.

Students will be introduced to a graphing calculator. Students will use a

graphing calculator to graph linear equations. They have already been graphing

using slope intercept form, as I expect them to have that down before they use

calculators.

Will review and reinforce PASS 2.2D (equation of a line), 2.2cII (use slopes to

differentiate between parallel and perpendicular), 1.1b (solve multivariable equations for

one variable in terms of the other), 2.4 (system of equations by graphing)

Instruction: Part 1 (suitable for 8

grade or Algebra 1)

Put an example on the board of a linear equation in slope intercept form

y = ½ x + 3 briefly review what is the slope and what is the y intercept

Pass out graphing calculators. Have the students set the windows for -10, 10,

with scales of 1. Explain to them how to do this and what it means.

Write the following sets of equations on the board

y = ¼ x + 2

y = ¼ x – 1

y = -2 x + 3

y = ½ x + 1

y = -x + 4

y = x + 4

y = 2/3 x – 3

y = -3/2 x + 4
