Graphing Linear Functions

Activity Overview

In this activity, students understand the concepts associated with the graphs of linear functions. They find and plot points, sketch graphs, and calculate gradient and intercepts.

Before the Activity

  • Download TI Connect™ using the TI Connectivity Cable
  • See the attached PDF file for detailed instructions for this activity
  • Print pages 1 - 3 from the attached PDF file for your class
  • During the Activity

    Distribute the pages to the class.

    Follow the Activity procedures:

  • Complete the given table of values for the given equations
  • Understand the concept of gradient
  • Identify the y-intercept
  • Use the calculator to set up a scatter plot for the points
  • Repeat the steps with different types of graphs with both positive and negative gradients
  • Look for patterns between the equation and its graph
  • After the Activity

    Students answer the questions on the activity sheet.

    Review student results:

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