Graphing linear inequalities in two variables
In this lesson, we will talk about how to solve linear inequalities as well as how to graph the solutions on number lines and the xy plane.
Basic Concepts: Express linear inequalities graphically and algebraically, Solving one-step linear inequalities, Solving multi-step linear inequalities, General form: Ax + By + C = 0
