Lesson 2 - Graphing Inequality Solutions

Graphing Inequalities

• Each symbol has a specific way to graph on a number line.

• There are 2 categories to consider when graphing:

• Circle Type: Open / Closed

• Direction: Left / Right

Included vs. Not Included

On a number line you can show if a solution or number is included by the dot used. Your dot will land on the number in the solution. There are 2 types:

+ Open Circle - meaning NOT included

+ Closed Circle - meaning IS included

Direction of the Arrow

• The Arrow goes in the same directions as your inequality symbol

• Left Arrow: < or <

• Right Arrow: > or >

Greater Than
