WebGraphing Inequalities on a Number Line Inequalities are exactly what they sound like: equations where the sides are "inequal" (not equal) to each other. There are five basic inequalities that we need to be familiar with: The inequality y < 2 means that y can be any number less than 2 (such as 1.9, 0.75, 0, -6, etc.). WebOct 6, 2024 · Shade the solutions on a number line and present the answer in interval notation. Here we use closed dots to indicate inclusive inequalities on the graph as follows: Figure 2.6.8 Answer: Using interval notation, [ − 6, 0] Exercise 2.6.3 Solve and graph the solution set: 3 + 4x − 5 < 8.
