Answer 1

A= (4;5) e B= (-5;5)

x;y x;y

$xm = \frac{x + x}{2} = \frac{4 - 5}{2} = \frac{-1}{2}$

$ym = \frac{y + y}{2} = \frac{5 + 5}{2} = \frac{10}{2} = 5$

Resposta: (-1/2;5)

M= (2;-7) e N= (2;1)

$xm = \frac{x + x}{2} = \frac{2 + 2}{2} = \frac{4}{2} = 2$

$ym = \frac{y + y}{2} = \frac{ - 7 + 1}{2} = \frac{ - 6}{2} = - 3$

Resposta: (2; -3)

X=( -5;-2) e Y=(7 ; 3)

$xm = \frac{x + x}{2} = \frac{ - 5 + 7}{2} = \frac{ - 2}{2} = - 1$

$ym = \frac{y +y }{2} = \frac{ - 2 + 3}{2} = \frac{ - 1}{2}$

Resposta: (-1; -1/2)

Espero ter ajudado.
