14.
The points which divides AB in the ratio 2:1 internally is
​

Answer 1

Answer:

ANSWER

The coordinates of point when (x1,y1) and (x2,y2) are divided in m:n

(i) internally is (m+nmx2+nx1,m+nmy2+ny1)

(ii) externally (m−nmx2−nx1,m−nmy2−ny1)

Let the point be P(h,k)

(1) For internal division 

h=2+32(4)+3(−1)=55=1k=2+32(−5)+3(2)=5−4⇒P(1,5−4)

(2) For external division

h=
