See Fig. 8. The numbers corresponding to the points on the line are called the coordinates of the points. The distance between two consecutive integers is called a unit, and it is the same for any two consecutive integers. The point with coordinate 0 is called the origin. The numbers on the number line increase in size from left to right. When we compare the size of any two numbers, the larger number lies to the right of the smaller one on the number line. 8 It is often convenient to illustrate sets of numbers on a number line.
