How do we interpret inequalities on a graph?

• First, see Inequalities and Straight Line Graphs

Once you do… 

1. Write down the?EQUATION?of each line on the graph
2. REMEMBER?that lines are drawn with: 

   A?solid?line for ≤ or ≥ (to indicate line included in region)A?dotted?line for < or > (to indicate line not included)

3. REPLACE?= sign with:≤ or < if shading?below?line ≥ or

   > if shading?above?line(Use a point to test if not sure)
