For the following coordinates of two points on a number line, state the distance between the points and .
The distance between the two points is 14.
The Distance can be calculated by taking the absolute value of the difference of coordinates of points. The absolute difference of two real numbers x and y can be calculated by . It describes the distance on the real line between the points corresponding to x and y.
Let and be the coordinates of two points .
Substitute for x and for y to determine the absolute value difference.
Hence, the distance between the two points is 14.
