Equalities assume two expressions are equal. Sometime though one expression is greater than or less than another. These are known as inequalities. Today's lesson helps you build the solution set for an inequality. This material is covered on pages 99-104 in the Engaging Algebra textbook.
2.5 The Solution Set for a Linear Inequality
Unlike a linear equation, which often has one solution, an inequality often has an infinite number of solutions. After this lesson you'll be able to use three common ways to express an infinite solution set.
