Graphing Systems of InequalitiesSo far in this inequalities unit, we have learned how to solve inequalities in one variable, and how to solve and graph inequalities in two variables. Now we are ready to move onto graphing systems of inequalities. This lesson shouldn't be too hard, because we are just going to apply all of our knowledge from graphing linear inequalities to create a system of inequalities. Let's take a look at our first example.
Example 1
Not too bad, is it? It might help for you to have two different colored pencils if you are practicing along with me. If you don't have colored pencils, then you can draw horizontal lines for one inequality and vertical lines for the other. This will make it easier to see which area contains solutions for both inequalities. The next example will demonstrate how to graph a horizontal and a vertical line.
Example 2
Ok... ready to try some on your own? If you can, try to use colored pencils or crayons. It will make your graphs easier to read! Gather your materials now, and meet me on the next page! See you there!

What People Are Saying..."I'd like to start off by relaying my sincerest gratitude for your dedication in teaching algebra. Your methodology is by far the simplest to follow, primarily because you take the time to include the small steps in between that most other teachers leave out. It helps to know why you are doing something. I am 45 and heading to college to get my BS in Business. I need to brush up, hence the visit to your site. Great Job!"
