Question

qual o valor do ponto médio do segmento (23,7) e (11,15)?

a)(11,4)
b)(8,4)
c)(4,5)
d)(8,11)
e)(4,11)​

Answer 1

Ponto médio é dado por:

$\boxed{x_m = \frac{x_1+x_2}{2}} \ e \ \boxed{y_m = \frac{y_1+y_2}{2}}$

Pontos:

    x   y

A(23, 7)

B(11, 15)

$\boxed{x_m = \frac{x_1+x_2}{2}} \ e \ \boxed{y_m = \frac{y_1+y_2}{2}} \\\\ x_m = \frac{23+11}{2} = \frac{34}{2} = \boxed{17} \\ y_m = \frac{7+15}{2} = \frac{22}{2} = \boxed{11} \\\\ \boxed{(x_m,y_m)=(17; 11)}$
