How are number lines and coordinate planes related?

Answer 1

Number lines and coordinate planes are both mathematical tools used to represent numbers and their relationships visually. A number line is a one-dimensional representation where each point corresponds to a real number, typically laid out horizontally. In contrast, a coordinate plane is a two-dimensional extension, where points are identified by pairs of numbers (coordinates) that specify their position along the horizontal (x-axis) and vertical (y-axis) lines. Essentially, the number line serves as a foundational concept for the axes of the coordinate plane.
