Question

Find the coordinate of trisecting points of line joining point (1, 6) and (−5,0).

Answer 1

Answer:

A(−3,0) B(6,6)

Let A(−3,0) be the first point and B(6,6) be the second point and P and Q be the internally trisecting point

Let AB=PQ=QB=K

PB=PQ+OB=2K

And AQ=AP+PQ=2K

AP=PB=1:2

And AQ:QB=2:1

P divides a,b internally in ratio 1:2 while Q divides internally in the ratio 2:1 does coordinates of p and q are
