(1) D = | M-N |, the distance between two points on the number axis is equal to the absolute value of the difference between the coordinates of the two points. (2) the distance d between two points a and B can be expressed as: | x + 1 |, if d = 3, that is, | x + 1 | = 3, x + 1 = 3 or x + 1 = - 3, x = 2 or - 4
