This can be used as an introduction to Systems of Equations. Students can work in groups or alone. They are shown graphs of the three different types of systems of equations and then asked to write equations of lines to create another set of systems.

The TNS file is all that is needed. Link this to each student Nspire handheld, they can work in a group or independently.

Have students create more questions similar to what they completed and have them switch handhelds with other students to complete.
