Final answer:
Solutions to an inequality, besides being graphed on a number line, can be represented using interval notation, set-builder notation, or inequality notation.
Step-by-step explanation:
Aside from graphing on the number line, the solution set to an inequality can be represented in various other ways. One common alternative is to use interval notation, which provides a concise mathematical way to describe the set of all numbers between two endpoints. Another method is to write the solution set in set-builder notation, which specifies the properties that members of the solution set must satisfy. Additionally, for more complex or multidimensional inequalities, representing solutions with inequality notation using greater than, less than, and equal signs can be very useful.
