Graphing Inequalities on the Number Line
Directions:[br][br]In the applet below, you'll see an inequality. Move the [color=#1551b5][b]BLUE POINT[/b][/color] above the number line below and adjust the [color=#c51414][b]red[/b][/color] and [color=#1551b5][b]blue[/b][/color] sliders (off to the top right) so that the graph you create is the graph of the inequality shown. [br][br][b]If you do this correctly, you'll see a "CORRECT!!!" symbol appear.[/b] [b]If you don't see a "CORRECT" icon appear, it means your graph is not yet correct. [/b] [br][br]Click on the "Generate New Inequality" button to generate a new inequality to graph. [br][br][i]Complete this exercise AS MANY TIMES AS YOU NEED in order to master this concept. [/i]
