Classwork: From yesterday...Students developed their understanding of linear relationships by investigating walkathons and how they're used to raise money for various reasons. We examined Alana (who earned $5 plus $.50 per kilometer), Gilberto (who earned $2 per kilometer) and Leanne (who earned $10 regardless of her distance). We created tables and graphed the relationships on a coordinate plane to more clearly understand each situation.
Today, we looked at the relationships and modeled them with equations. We identified independent and dependent variables to help us in that effort.
