Question

Determine M, ponto médio de AB, nos seguintes casos:

a) A (3, -2) e B (-1, -6)

b) A (0,7) e B(6,0)

Answer 1

Olá, tudo bem.

Considerando $M( x_{M} , y_{M} )$, temos:

a) 

$x_{M} = \frac{3 +(-1)}{2} = \frac{2}{2} = 1$

$y_{M} = \frac{-2 + (-6)}{2} = \frac{-8}{2} = -4$

$M (1, -4)$

b)

$x_{M} = \frac{0 + 6}{2} = \frac{6}{2} = 3$

$y_{M} = \frac{7 + 0}{2} = \frac{7}{2} = 3 \frac{1}{2}$

$M ( 3 , \frac{7}{2} )$  ou  $M (3, 3 \frac{1}{2} )$

Abraço!
