This unit was taught to my 7th grade Algebra students. In this unit, students explore linear relationships in tables, graphs, and equations. We learned to write equations using a point-tester method, in which we test a point on the line and the point (x, y) in the slope formula, then use the rules of Algebra to re-write the equation in different forms. We also used the Desmos online graphing calculator to explore the relationship between linear equations and graphs.
