Question 982763: Use the Distance Formula and the x-axis of the coordinate plane. Show why the distance between two points on a number line (the x-axis) is | a – b |, where a and b are the x-coordinates of the points

Vertical coordinates are 0 while horizontal components would be two values neither necessarily being zero.
Points (a,0) and (b,0);
Without getting into too much more detailed discussion, main result of that expression is (a-b).
