How it works ?
This applet was designed to help you graph solution sets (to linear inequalities or systems of linear inequalities) that are written in INTERVAL NOTATION.
Adjust the POSSIBILITY SELECTOR slider and move any one (or more) of the points above the number line around so that the graph of the solution set you construct matches the set of values written in interval notation above.
Once you do this correctly, you’ll see a big “CORRECT !!!” sign appear.
