Coordinates of Points Calculator finds the dividing line segments (ratios of directed line segments). It finds the coordinates using partitioning a line segment. The Coordinates of points is determined a pair of numbers defining the position of a point that defines its exact location on a two-dimensional plane.

Using partition calculator - Ratio formula or section formula is used to find the coordinates of a point P which divides the segment joining the points A and B internally or externally in the ratio m : n.

Case 1: **Find the coordinates of the point which divides the line joining the points (2, 3), (4, 5) internally in the ratio 2:1.**

x1 = 2, y1 = 3 and

x2 = 4, y2 = 5

m = 2, n = 1

**Apply Formula**

(mx2+nx1/m+n , my2+ny1/m+n)

(2*4+1*2/2+1 , 2*5+1*3/2+1)

(8+2/3 , 10+3/3 )

(10/3 , 13/3)

**(3.3 , 4.3)**

Case 2: **Find the coordinates of the point which divides the line joining the points (2, 1), (3, 4) externally in the ratio 2:5.**

x1 = 2, y1 = 1 and

x2 = 3, y2 = 4

m = 2, n = 5
