The distance formula is derived from the pythagorean theorem|dw:1318033031424:dw|To find the distance between points A and B we can start with the pythagorean theorem$$d(AB)^2=(y _{2}-y _{1})^2+(x _{2}-x _{1})^2$$where the sides lengths of the right triangle are defined in the drawing above.  This gives us diastase squared, so we can take the positive square root of both sides to get the d(AB)$$d(AB)=\sqrt{(y _{2}-y _{1})^2+(x _{2}-x _{1})^2}$$
