A number line is a straight, horizontal line that represents numbers at equal intervals. It typically includes positive and negative numbers, with zero at the center. Points on the line correspond to real numbers, and the distance between any two points indicates the difference between those numbers. Number lines can also include markings for fractions, decimals, or other mathematical concepts.
