By the end of this lesson, you will be able to identify and graph a system of linear inequalities.

This tutorial walks students briefly through how to graph systems of linear inequalities. Then goes over the number of solutions and types of systems that can be created using multiple inequalities.

Tutorial

1) **Watch the podcast & take notes**

NOTES - Cornell Style on p.15

Questions are given in the podcast

Title: Systems of Inequalities

2) **Explore the tutorial page**

Watch the prezi and look at the concept map from the notes

Check out other websites and videos about systems of inequalities

Review the vocabulary from the unit

3) **Work Time**

- Assignment: graph systems of inequalities with clear boundary lines and neat shading

- Vocabulary: on the back of your vocabulary table add BOUNDED and OPEN, use the definitions from the

webpage and add sentences

This podcast introduces students to graphing systems of inequalities as well as the different types of systems of inequalities - no solution systems, infinite solution systems, as well as, bounded and open systems.

This podcast assumes students have graphed linear inequalities before.

The slides of the podcast about graphing systems of inequalities.

**BOUNDARY LINE:** The line that separates the solutions from the non-solutions for an inequality

**BOUNDED:** A system of inequalities where all solutions are contained in an area by the inequalities.

**INEQUALITY**:** **A symbol that shows a mathematical relationship is not equal ( < , > , __<__ , __>__ )

**OPEN:** A system of inequalities where the solutions continue on forever.

**SOLUTION:** An ordered pair or pairs that make all inequalities in a system true.

**SYSTEM:** A set of two or more inequalities with the same variable.
