Graphing and Solving Two-Step Inequalities

This video tutorial covers how to graph and solve two-step inequalities. It begins with an introduction to inequalities, explaining the difference between open and closed circles on a graph. The tutorial provides examples of graphing inequalities on a number line and explains the steps to solve two-step inequalities, emphasizing the importance of flipping the inequality symbol when multiplying or dividing by a negative number. The video includes practice problems to reinforce the concepts taught.

What does an open circle on a graph indicate?

• The solution is positive

• The solution is zero

• The solution is not included

• The solution is included
