I got x = 8, y =7. But getting different answer for centroid coordinate by using the centroid formula. Answer is given as G:(8,7). Can anyone explain how it is so?

hmmm When you are using the centroid formula, you are accounting for the fact that it lies on the line but it may also lie lie outside the triangle, by distance formula. something like this. this explains the 'other' answer dw:1334301731285:dw so unless you put the constraint that it lies on th eline. you are have two loci of 'G'.

since coordinate of G on the line xy=1. hence let y coordinate=h of centroid. xh=1. there fore x=h+1..hence it will be x coordinate of the centroid.
