Instructional Ideas

• Have the class write down all the points of intersection and the system in whcih they are a solution

Classroom Considerations

• The class should be comfortable graphing lines in slope-intercept form
• Users need to sign up for a free CK-12 account

Pros

• The supplemental material shows how to graph a linear system using technology
• Allows students to adjust the red dots, making it easier to graph the lines

Cons

• None
