Given the points H(6,7) and I(-7,-6).
If point G lies
of the way along line segment HI.
Therefore, we can say that the point G divides the line segment HI in the ratio 1:1.
So, by using the cross section formula we can determine the coordinates of point G.
For the given points say
and
divided is in the ratio
, the coordinates are 
Coordinates G = 
= (-0.5 , 0.5)
Hence, the coordinates of G are (-0.5 , 0.5).
So, Santiago argues that point G is located at the origin. The point G is located at (-0.5, 0.5). Therefore, he is not correct.
= -1/2- (-2/5)
= -1/2 + 2/5
find common denominator (2 goes in 10 five times; 5 goes in 10 twice)
= -(5*1)/10 + (2*2)/10
= -5/10 + 4/10
= -1/10
Hope this helps! :)
