This is the second part of the video series “How do you solve and graph linear inequalities in one variable?” In this video, you will learn how to solve linear inequalities in one variable algebraically and graphically. You will also learn how to translate word problems into inequalities and use a Four-Step Method in solving the inequality in a problem-solving context.
How do you solve and graph linear inequalities in one variable? This video will show you how to graph solution sets of inequalities in one variable. The video also discusses the effect of performing a given operation on each side of the inequality on the sense of the original inequality. You will learn when to reverse the order of the inequality and in which operation.
How do you solve linear equations with a variable on both sides? This video will show how to use linear equations with a variable on both sides to solve a data plan problem. The video also models how to solve equations that have no solution, one solution, and infinitely many solutions.
