What a plotted number line?

A plotted number line is a visual representation of numbers arranged in a straight line, where each point corresponds to a specific value. It typically includes markers for whole numbers, fractions, or decimals, allowing for easy comparison and understanding of numerical relationships. The line extends infinitely in both directions, with arrows indicating the continuation of values beyond the visible range. This tool is often used in mathematics to illustrate concepts such as addition, subtraction, and the ordering of numbers.
