Interpret graphs or figures

CONCEPTS

Method to interpret inequality graphs

1. Rearrange the equation so “y” is on the left and everything else is on the right

2. Plot the “y =” line (make it a solid for y ≥ or y ≤ and a dashed for y > or y <)

3. Shade above the line for “greater than” (y > or ≥) and below for “less than” (≤ or <)
