The centroid ? (1,2) , circumcentre?(-2,1) ,then coordinate of orthocenter is ?

As we know that centroid divides the line joining the circumcenter and the orthocenter in the ratio 1:2 .

So Let orthocenter be(x,y)

1 = (x - 4)/3       ,   2 = (y + 2)/3

x = 7                  ,    y = 4

Orthocenetr is (7,4)
