Standards:

Duration to complete: 10-15 minutes

Learning outcome: Students will be able to graph linear equations, find their intersection, and will understand that this intersection is the solution to the system of equations.

In the Classroom

Pre-Experience (Things to Look Out For):

• Let’s recap some line graphing skills: what do m and b stand for in the equation y = mx + b ?

• What is a system of equations?

• How do you think you might solve a system of equations?

Post-Experience (Things to Think About):

• When is there a solution to a system of equations? When is there not?

• What can be said about lines that produce an infinite number of solutions?

• What do you notice about parallel lines?

• What sort of scenarios could a system of equations model?

• How do you think this method could be used to solve a system of equations with more than two lines?
