Answer:
there are two cases
let us take a line segment AB
let the points p,q points of trisection AB
AP=PQ=QB
case 1: p divides AB in the ratio 1:2=m:n
case :2 : Q divides AB in the ratio 2:1=m:n
the formula is p(x,y)=[mx2+nx1÷m+n,my2+ny1÷m+n]

⠀⠀⠀(2,6)A⠀⠀⠀P⠀⠀⠀⠀⠀⠀Q⠀⠀B(-4,8)
p divides the line segment in 1:2.
m1=1,⠀⠀⠀⠀m2=2
by using section formula
x=⠀⠀⠀(m1x2+m2x1)
⠀⠀⠀⠀⠀-------------------
⠀⠀⠀⠀⠀⠀⠀m1+m2⠀⠀

y=⠀⠀⠀⠀(m1y2+m2y1)

⠀⠀⠀⠀⠀⠀⠀⠀m1+m2

p=(0,20/3)
Q=(-2,14/3)
