2. Essential Questions How does representing functions graphically help you solve a system of equations? Students will solve a system of linear equations by graphing the equations to find the point(s) of intersection. How does writing equivalent equations help you solve a system of equations? Students will use substitution and elimination methods to write equivalent equations until they get an equation with only one variable.
