Example - 3 : Find the coordinate of the point which divides the line joining (6, 7) and (-1, 0) in the ration of 2: 5.

Solution :- Let m : n = 2 : 5 and coordinates of the point be (x, y)

Example - 4 : Find the coordinates of the centroid of a triangle whose vertices are A (x₁, y₁), B(x₂, y₂) and C (x₃, y₃)

Solution : - Let AM be a medium

If G be the centroid of the triangle then AG ; GM = 2 : 1. Let co-ordinatess of G be (X, Y)
