Number Line

Number Line

Directed and graduated line or ray used to support the graphic representation of a set of numbers.


A number axis is represented by a directed and graduated ray on which the x-coordinate of the numbers are usually displayed under each graduation. An arrow at one end indicates the increasing order of the axis.


In this figure, each graduation represents a multiple of 5. The x-coordinate of the point A is 30, so the x-coordinate of point B is 50.
