Now that students have mastered graphing of individual points on the Cartesian Plane, they advance to graphing linear equations with two variables. With each line having an infinite set of points, students are asked to find three points to satisfy a given equation. They learn what "Function Form" is and are able at the conclusion of the lesson to manipulate an equation from standard form to function form. Once the equation is in function form, students make a table and find values for x and y that will serve as solutions to the equation. The ordered pairs, or solutions, are then graphed on the Cartesian Plane. The final portion of the lesson is a real-life situation involving an individual training for a triathlon and the number of calories burned while training. Your students will find this lesson both challenging and an "infinite" pleasure all at the same time! Happy teaching!
