Graphing Systems of Inequalities
So 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.
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.
