<div itemprop="text">

From the figure, it can be observed that points X, Y, Z are dividing the line segment in a ratio 1:3, 1:1, 3:1 respectively.
Coordinates of x = {tex}\;\left(\frac{1\times2+3(-2)}{1\;+\;3},\frac{1\times8\;+3\times2}{1+\;3}\right)=\;\left(-1,\;\frac72\right){/tex}
Coordinate of Y = {tex}\;\left(\frac{2 +(-2)}{2},\frac{2 +8}{2}\right)=(0,5){/tex}
Coordinate of Z = {tex}\;\left(\frac{3\times2+1(-2)}{1\;+\;3},\frac{3\times8\;+1\times2}{1+\;3}\right)=\;\left(\;1,\;\frac{13}2\right){/tex}
