Graphing Solutions to Equations and Inequalities

Topics for Today:

Today we started a unit on graphing by discussing what a graph is, and also the difference between solutions of an equation and solutions of an inequality.  We also solved simple inequalities using addition and subtraction.

Our graphing focused on number lines.  We will be working with the coordinate system (all four quadrants) in the upcoming days.  

Vocabulary:

coordinate, graph, inequality, solution of an inequality
