Question 416438: what is the use of number line

The number line is a visual way to see and sort all of the real numbers. It's also a way to correspond numbers to measurements and distances. For instance, if you live at 0 and you walk to 7, then you have traveled a distance of 7 units. You can also think of the number line as a time line (where time zero is the beginning).
