Graphing Systems of Linear Inequalities - Example 2
By PatrickJMT
In this video, the instructor goes through the steps needed to graph a system of linear inequalities. He discusses slope, shows how to draw the line on the coordinate plane, and explains what section of the graph should be shaded. There is some shadow on the white board which makes it a little more difficult to see at times during the instruction.
