A number line helps us express our algebraic work with real numbers. Numbers define amounts, distances, ages, temperatures, and more. Decimals, fractions, and integers are real numbers. They might be sensible or crazy, depending on the context. Imaginary numbers are not real. Imagined numbers let mathematicians describe numbers not on a number line.
