Question

P and Q are the points with co-ordinates (2, -1) and (-3, 4). Find the coordinates of the point R such that PR is 2/5 of PQ.

Answer 1

Point R divides PQ in ratio 2:3. 

Co-ordinates of point R are given by 

 x = (2 x - 3 + 3 x 2)/5=0 

y = (2 x 4 + 3 x -1)/5=1

So, the required point R is (0,1)
