3.3 Systems of Linear Inequalities
• What does the graph of a system of inequalities
tell you?
• Where is the answer found for a system of
inequalities?

3
Graphing a System of Linear Inequalities
• Graph the line that corresponds to the
inequality. Use a dashed line for an inequality
with lt or gt and a solid line for an inequality
with or .
• Lightly shade the half-plane that is the graph of
distinguish the different half-planes.
• The graph of the system is the region common
to all of the half-planes.
