Solving and Graphing Inequalities
Inequalities are useful for finding a range of solutions. Solving and graphing inequalities is a key to finding and showing that range. This video clip explains how to solve inequalities using a lot of the same methods as those in solving multi-step equations when dealing with additive inverses, although some things are different when solving inequalities using multiplication. We graph inequalities using number lines. (1:32)

Graphing Inequalities in Two Variables
This is a video tutorial of how to graph and shade inequalities involving two variables.Â  Instead of using a number line, the inequality is graphed on an x,y graph.Â  The instructor relates what is know about graphing equalities and applies this knowledge to graphing inequalities.Â  He works quickly through examples and doesn't show all of the steps needed in drawing the lines on the graph.

Graphing Systems of Linear Inequalities
InÂ  this video, the instructor goes through the steps needed to graph a system of linear inequalities.Â  He discusses slope, shows how to draw the line on the coordinate plane, and explains what section of the graph should be shaded.Â  There is some shadow on the white board which makes it a little more difficult to see at times during the instruction.

Solving and Graphing Multi-Step Inequalities
Sometimes we get more complex inequalities that take more than one step to solve. This video clip explains how to solve multi-step inequalities by using addition and multiplication. Many of the techniques are similar to those learned when solving multi-step equations. (1:11)
