The number 2 will work, as will −2. But 4 will not work, and neither will −4, because they are too far away from zero.

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 · Two common ways of expressing solutions to an inequality are by graphing them on a number line and using interval notation.
