The intersection of medians of a triangle is the "center of masses" of the triangle.
It is also called "centroid" and/or "barycenter".
Very well and widely known fact is that this point has coordinates (Xc,Yc), where
Xc = ,
Yc = .
In our case, Xc = = = 4 and Yc = = = 1.
So, the intersection of medians is the point (4,1).
