Khan Academy: Graphing Linear Inequalities: Graphing Inequalities

This video demonstrates how to solve several test questions related to linear equations and linear inequalities.

This video demonstrates how to write a two variable inequality given the graph of the inequality on a coordinate plane.

So, exactly, what does it look like? The easily usable graphing calculator allows pupils to visualize the graph of equations and inequalities. The interactive supports any algebraic graph needed for high school mathematics and then some.

So many methods and so little time! The efficient method of graphing a linear equation depends on what information the problem gives. Pupils learn three different methods of graphing linear equations. They graph equations using...

You just crossed the boundary line, the inequality boundary line that is. Watch and refresh your memory on the process needed to graph and solve a linear inequality. This is a short, slow, and easy to follow video that could help before...

Watch [3:26] Sal work through a harder Graphing linear equations problem.

Watch [2:37] Sal work through a basic Graphing linear equations problem.

Video giving step-by-step instructions on how to solve inequalities. Example problem includes reversing the inequality when dividing by a negative number. [4:32]

This video demonstrates how to graph an inequality with two variables and check your graph by substituting ordered pairs back into the inequality. Practice problems available. [5:20]

This video demonstrates how to determine if a set of ordered pairs is a solution to a two variable inequality. First the video shows how to plug the ordered pair into the inequality and solve, then the video demonstrates how to graph the...
