Question

Determine as coordenadas do ponto médio do segmento cujas extremidades são os pontos :


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

B) b (3, -4) e M (3, 2)

Answer 1

A) a(-1,-1) e b(-3, 3)

$x_m = \frac{-1+ (-3)}{2} \\\\ x_m = \frac{-4}{2} \\\\\boxed{ x_m = -2}\\\\\\y_m = \frac{-1 + 3}{2} \\\\y_m = \frac{2}{2} \\\\\boxed{y_m = 1}$

Portanto o ponto médio m(-2, 1).

B) b(3, -4) e m (3, 2)

$x_m = \frac{3 + 3}{2} \\\\ x_m = \frac{6}{2} \\\\ \boxed{x_m = 3}\\\\\\y_m = \frac{-4 + 2}{2} \\\\y_m = \frac{-2}{2} \\\\ \boxed{y_m = -1}$

Portanto o onto médio é P(3, -1)
