Lesson
7-1 Solving Systems by Graphing
Objective
(MA.C.3.4.2) To graph, apply, and verify properties of two-and three-dimensional figures.
(MA.C.3.4.2, MA.D.2.4.2) To use systems of equations to solve real-world problems.

Circulatory system...

Lots of arteries and veins working together.
Skeletal system...

Not just one bone, many bones
Muscular system...

Many, many muscles

A system of linear equations is two or more linear equations together.
Any ordered pair that makes all the equations true is a solution of the system of linear equations.

There are many ways to solve a system of equations.
We will discuss three of them in Chapter 7: Systems of Equations and Inequalities
1. Graphing
2. Substitution
3. Elimination

Lesson
7.4 Systems of Inequalities
Objectives: Students will know how to sketch the graphs of inequalities in two variables and how to solve systems of inequalities.

I. The graph of an inequality (pp.525 - 526)
Example 1 - Sketching the graph of an inequality
Example 2 - Sketching the graphs of linear inequalities
Example 3 - Sketching the graph of a linear inequality
Watch a video tutorial about graphing linear inequalities.

II. Systems of Inequalities (pp. 527 - 529)
To graph a system of inequalities we graph eah inequality in the system, and where the shaded regions all overlap is the solution region.
Example 4 - Solving a system of inequalities
