## Introductory Algebra for College Students (7th Edition)

The distance from 0 to 1 is called the unit distance. Numbers to the right of the origin (0) are positive and numbers to the left of the origin are negative. Real numbers are graphed on a number line by placing a dot at the correct location for each number. The number $\displaystyle \frac{7}{3}=2\frac{1}{3}$ is positive, and is located $2\displaystyle \frac{1}{3}$ units to the right of 0. (Or, one third the unit distance to the right of $2$)
