Question

calcules as coordenadas de M, ponto médio do seguimento AB, quando A (7,9) e B ( -2,5)

Answer 1

$x_M=\frac{x_A+x_B}{2}=\frac{7-2}{2}=\frac{5}{2} \\ \\ y_M=\frac{y_A+y_B}{2}=\frac{9+5}{2}=7 \\ \\ \boxed{M\left(\frac{5}{2},7\right)}$

Answer 2

Para calcular o ponto médio vc utiliza dessa formula: M= ((xa+xb)/2 , (ya+yb)/2)

$M= (\frac{7-2}{2} , \frac{9+5}{2}) => M=( \frac{5}{2},7)$
