What is the distance between points A and B?

By definition, the formula to find the distance between two points, is given by:
 d = root ((x2-x1) ^ 2 + (y2-y1) ^ 2)
 The ordered pairs as they are located on a line are:
 (x1, y1) = (- 5.0)
 (x2, y2) = (1,0)
 By applying the formula we have:
 d = root ((1 - (- 5)) ^ 2 + (0-0) ^ 2)
 d = 6
 Answer:
 the distance between points A and B is:
 d = 6 units
