The video tutorial by Miss Casillas covers solving and graphing one and two-step inequalities. It explains the process of solving inequalities using similar steps as equations, with the key difference being the need to flip the inequality sign when multiplying or dividing by a negative number. The tutorial also demonstrates how to graph inequalities on a number line, using open or closed circles based on the inequality type. Several examples are provided to illustrate these concepts, including a real-world application involving budgeting for pizza delivery.

What must be done to the inequality sign when multiplying or dividing by a negative number?

• Replace it with an equal sign

• Remove the sign

• Keep the sign unchanged

• Flip the sign
