Recall that the Ruler Postulate states that on a number line, the distance between two points is determined by the absolute value of the difference between their coordinates.
distance formula, Algebraic expression that gives the distances between pairs of points in terms of their coordinates (see coordinate system). ... In three dimensional space, the distance between the points (a, b, c) and (d, e, f) is Square root of√(a − d)2 + (b − e)2 + (c − f)2.
