Question

formula for internal division

Answer 1

if a line is divided internally in m:n by a point then the coordinate of point is given by-

x=mx2-nx1/m+n ,y=my2-ny1/m+n

its coordinate can be found by this formula

Answer 2

HELLO DEAR,



If there are two points P(x1,y1) and Q(x2,y2),, and the line segment PQis divided internally by point R(x,y) in the ratio m:n,then, the coordinates of R(x,y) are as under:

$x = \frac{mx _{2} + n x_{1}}{m + n} \\ = > y = \frac{m y_{2} + n y_{1} }{m + n}$
I HOPE ITS HELP YOU DEAR,
THANKS
