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.

Introduction to graphing inequalities | Two-variable linear inequalities | Algebra I | Khan Academy
By Khan Academy
This video from Khan Academy demonstrates how to graph inequalities. Sal completes some example problems to show you how it's done.
Check solutions of two-variable linear inequalities
By Khan Academy
Sal determines whether the ordered pairs (3,5) and (1,-7) are solutions of the inequality 5x-3y���������������������25. He discussed the problem both algebraically and graphically.
Constraint solution sets of systems of linear inequalities
By Khan Academy
Given the graph of a system of inequalities, Sal finds the x-values that make the ordered pair (x,-2) a solution of the system, which is the solution set constrained to y=-2. Then he solves a similar problem where x is constrained to 4.
Constraint solution sets of two-variable linear inequalities
By Khan Academy
Sal determines which x-values make the ordered pair (x,-7) a solution of 2x-7y<25. He also solves a similar problem where the inequality is given as a graph.
