Answer:

T divides PQ in ratio=2:7

Explanation:

  • co-ordinate of P= [( mx2 + nx1)/( m+n),( my2+ ny1)/(m+n)].Here,T(-16) divides line segment joining pointsP(-3,10) andQ(6,-8).
  • Let T divides PQ in m:n ratio then,
  1. -1=[m×6+n×(-3) ]/ m+ n
  2. -1( m+n) = 6m-3n
  3. -m -n =6m-3n
  4. -7m= -2n

So,m/n= 2/7

Therefore, T divides PQ in ratio2:7
