Ponto médio:  \frac{x2-x1}{2} /  \frac{y2+y1}{2}

AB = Ym= \frac{7-3}{2} =  \frac{4}{2} = 2
   
  = Xm =  \frac{1-11}{2} =  \frac{-10}{2} = -5

Xm = (Xa + Xb)/2 

Ym = (Ya + Yb)/2 

---------------------------------
Xm= (1+11)/2 = 12/2 = 6
---------------------------------
Ym=(7+3/2= 8/2 = 4

(X,Y) = (6,4)
