Graphing Linear Inequalities

Click on the checkbox to show the inequality. Move the Test Point (T1) to find the points that make the inequality true.

Sorry, the GeoGebra Applet could not be started. Please make sure that Java 1.4.2 (or later) is installed and active in your browser (Click here to install Java now)

Change the values for the slope and y-intercept for each inequality. What do you notice about where the test point (T1) is true?
