Q. 9

P and Q are the p

Answer :

Given,



As, PQ = PR + RQ


We have,







PR : RQ = 2 : 3


i.e. R divides PQ in 2 : 3


Using section formula, i.e.


The coordinates of Point R which divides line PQ in a ration m : n is



Where, (x1, y1) and (x2, y2) are the coordinates of points P and Q respectively.


We have, P(2, -1), Q(-3, 4) and ratio is 2 : 3




Hence, coordinates of R is (0, 1)
