 * Solving Systems of Linear Equations - Two special cases **

1. Use your Gizmo and change the values of the coefficients to create a system that is parallel. 2. Click over to the Solutions Tab and look over how they solved this system using substitution. 3. What happened to the variable? Why? 4. What was the resulting equation? Is that a true statement? Is there a solution? Why or Why not? 5. Discuss with the other half of your group the final equation. Did you all get the same final equation? 6. Go back and create another system that is parallel and compare the results. What happened?

Answer the same questions above given a system where the two equations are the same line.

When you've seen both special cases discuss with your group what kind of results you will get if
 * the system is parallel
 * the system is the same line
