Lesson Summary:

In this lesson, Julie Harland introduces linear inequalities with two variables and teaches how to graph them. She explains that the graph of an equation is simply showing all the solutions to the equation, and similarly, the graph of an inequality shows all the solutions that make the inequality true. The lesson provides a step-by-step method for graphing linear inequalities and provides helpful tips for determining which side of the line to shade. Students are also given practice problems to check their understanding.

Lesson Description:

Part 1 is an introduction to graphing linear inequalities with 2 variables.

    This lesson uses the concept of graphing a line to introduce how to graph a linear inequality in a coordinate plane. First, you will learn how to determine whether some points satisfy the inequality. Then, you will learn how to graph the line and determine which side of the line to shade.
