Topic: Linear functions and modeling

Resource type: In-Class Activity Time Required: 30 minutes Content: Critical thinking/ concept development Materials: graph paper DESCRIPTION: Students will be presented with two different gas stations, and will have to come up with equations to determine the price of gas at each. They will do this by first calculating a few values, then using that process to come up with a general equation for each. The equations will be graphed in order to see the "break-even point", and this will be followed by a discussion of methods for finding solutions to systems of equations.
