Lesson Description:

This video is on graphing systems of linear, 2 variable inequalities in the coordinate plane.

This vid was created using Jing by TechSmith & with the help of Ian Vogt's linear equation / inequality graphing applet(http://mathgraph.idwvogt.com/GraphPpr.html) for graphing.

    This lesson goes through an excellent example of graphing 4 different linear inequalities on the same graph, shading, and finding the intersection of all 4 shaded areas. All steps for graphing the lines and shading are explained very well. Unfortunately, the video cuts out at 5:00, although the instruction is basically finished.

    I only wish I could HEAR the lesson! From the Staff Review, it sounds like it'd really help me right now... but the volume is too low even when I turn up my laptop volume and the volume on screen...
