In the Closest Pair Brute Force algorithm, the objective is to find the closest pair of points from the given points in the x-y plane. Normally the point is easily represented using coordinate x and coordinate y. For the example, p1 = (x1,y1).

Please show the working steps how to calculate the distance between these two points which are p1 = (3,5) and p2 = (7, 10).

What is the name of the distance formula?
