Quickstart
p.524 #127 - 133 odd
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
Example 5 - Solving a system of inequalities
