7P3= 7!/(7-3)!
= 7!/4!
= 7*6*5
= 210

Given:
The endpoints of a line segment are (-5,12) and (-5,0).
To find:
The coordinates of a points which divides the line segment in 2:1.
Solution:
Section formula: If a point divides a line segment in m:n.

Let point P divides the given line segment in 2:1. They, by using section formula, we get




Therefore, the coordinate of the point that partitions the given segment in the ratio 2:1 are (-5,4).
