In this lesson, students learn how to solve and graph an absolute value inequality by representing it as two solutions and solving both ways. The teacher emphasizes the importance of changing signs when dealing with inequality, and shows step-by-step how to solve a compound inequality. Students also learn how to graph the solution on a number line by using open and closed circles and shading the appropriate area.
Solving and graphing an inequality as an absolute value
I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
