Linear Inequalities
This resources is a video of a teacher introducing linear inequalities. She takes about 7 minutes to introduce the vocabulary and notation used for inequalites. She also explains the concept of graphing the inequalities. She explains how to use open and closed circles to graph inequalities on a number line. She also explains that when you graph with two variables, a Cartesian Coordinate plane is used. This is a great resource to use as an introduction to inequalties.
This resource lays the foundation for solving and graphing a linear inequality.
