Draw a figure, line dividing by 4 points.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=(1+31(2)+3(−2)​,1+31(8)+3(2)​)=(−1,7/2) Coordinates of Y=(1+12(1)−2(1)​,1+12(1)+8(1)​)=(0,5) Coordinates of Z=(1+33(2)+1(−2)​,1+33(8)+1(2)​)=(1,13/2)
