let, a=(-7,1)=(x1,y1)

b=(5,-5)=(x2,y2)

c=(1,7)=(x3,y3)

orthocentre is centroid

centroid = ( \frac{x1 + x2 + r3}{3}  +  \frac{y1 + y2 + y3}{3} ) \\  \\  = ( \frac{ - 7 + 5 + 1}{3}  +  \frac{1 + ( - 5) + 7}{3} ) \\  \\  = ( \frac{ - 1}{3}  +  \frac{3}{3} ) \\  \\  =   \frac{ - 1 + 3}{3}  \\  \\  =  \frac{2}{3}
orthocentre = 2/3
