Answer 1

Fómula:

$(\frac{x1+x2}{2},\frac{y1+y2}{2})$

Basta somar os mesmos eixos e dividi-los por 2!

$A(X_1, Y_1)\\ B(X_2, Y_2)$

A) A(2, -3) e B(-2, 1)

$(\frac{2+(-2)}{2},\frac{-3+1}{2} )=(\frac{0}{2},\frac{-2}{2} )=(0, -1)$

B) A (-1,2) e B (-2,0)

$(\frac{-1+(-2)}{2},\frac{2+0}{2} )=(\frac{-3}{2},\frac{2}{2} )=(-1.5, 1)$

C) A (-3,3) e B (-4,3)  

$(\frac{-3+(-4)}{2},\frac{3+3}{2} )=(\frac{-7}{2},\frac{6}{2} )=(-3.5, 3)$

D) A (4,2) e B (2,4)

$(\frac{4+2}{2},\frac{2+4}{2} )=(\frac{6}{2},\frac{6}{2} )=(3, 3)$

O resto é só adaptar!
