Answer:
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
P(
1+2
1(6)+2×(−3)
,
1+2
1(6)+2(0)
)=P(0,2)
Q(
1+2
2(6)+1×(−3)
,
1+2
2(6)+1(0)
)=Q(

)=Q(3,4)
P(0,2) and Q(3,4) are point of trisection
