1. 9.6 Systems of Inequalities
Chapter 9 Systems and Matrices
2. Concepts and Objectives
⚫ Systems of Inequalities
⚫ Graph systems of inequalities
⚫ Identify solutions to systems of inequalities
3. Graphing Review
⚫ To graph a linear inequality, put the inequality into
slope-intercept form.
⚫ Plot the y-intercept and count the slope from there
(rise over run)

8. Systems of Inequalities
⚫ The solution to a system of inequalities will be the graph
of the overlap between the two (or more) inequalities.
⚫ You must graph the system to show the solution.
⚫ If the inequalities do not overlap, then there is no
solution to the system.
