Question

determine as coordernadas do ponto medio do segmento AB A(1,7) E B(11,3) b. A(3-1) e B(-2,1) .

Answer 1

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

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

Answer 2

Xm = (Xa + Xb)/2 
e 
Ym = (Ya + Yb)/2 

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

(X,Y) = (6,4)
