Question

Determine o ponto médio:
a)A(-10,5) e B(-8,-4)

Answer 1

Resposta:

$\frac{xa + xb}{2} \: \: \frac{ya + yb}{2} = m$

$\frac{ - 10 + ( - 8)}{2} = \frac{ - 18}{2} = - 9$

$\frac{5 + ( - 4)}{2} = \frac{1}{2} = \frac{1}{2} = m \: \: \: ou \: \: \: 0.5 = m$

$m = ( - 9 \: , \frac{1}{2} ) \: \: ou \: \: \: \: m = ( - 9 \: , \: 0,5)$
