Question

how to find distances between two points on a number of line

Answer 1

by measuring with scale

Answer 2

An absolute value is the positive representation for a number and is symbolized as |a|. For example, the absolute values of 3 and -3, or |3| and |-3|, are both 3. This method of number line distance works for numbers close together and far apart.

Select two numbers on the number line. For this example, the numbers are -9 and 5.

Subtract one number on the number line from the other number. For this example, -9 subtracted from 5 is 14. If subtracting 5 from -9, the answer would be -14.
