Question

Sejam A(-20,-6) e B(12,-4) pontos no plano. O ponto médio do segmento AB

Answer 1

Resposta:

A(-20,-6) e B(12,-4)

Pm=[(x1+x2)/2 ; (y1+y2)/2]

Pm=[(-20+12)/2 ; (-6-4)/2]

Pm=(-4 ; -5)

Answer 2

Resposta:

M(-4, -5)

Explicação passo a passo:

Seja M(x, y) o ponto médio:

$x_M=\frac{x_A+x_B}{2} \\\\x_M=\frac{-20+12}{2} \\\\x_M=\frac{-8}{2}1\\\\x_M=-4\\\\y_M=\frac{y_A+y_B}{2} \\\\y_M=\frac{-6-4}{2}\\\\y_M=\frac{-10}{2}\\\\y_M=-5\\\\M(-4,-5)$
