Step-by-step explanation:
When a point C divides a segment AB in the ratio m:n, we use the section formula to find the coordinates of that point. The section formula has 2 types. These types depend on the position of point C. It can be present between the 2 points or outside the segment.
The two types are:
Internal Section Formula
External Section Formula
Internal Section Formula
Also known as the Section Formula for Internal Division. When the line segment is divided internally in the ration m:n, we use this formula. That is when the point C lies somewhere between the points A and B. Understand the concept of Coordinate here.

The Coordinates of point C will be,
{[(mx2+nx1)/(m+n)],[(my2+ny1)/(m+n)]}
Breaking it down, the x coordinate is (mx2+nx1)/(m+n) and the y coordinate is (my2+ny1)/(m+n)
