Question

dados os pontos P(5, 1) e Q(-2, -9), dertemine as coordenadas do ponto medio do seguinte PQ

Answer 1

$pm= \left(\dfrac{x_1+x_2}{2}, \dfrac{y_1+y_2}{2}\right)\\\\ pm=\left\{ \dfrac{5+(-2)}{2}, \dfrac{1+(-9)}{2}\right\}\\\\ pm=\left( \dfrac{5-2}{2}, \dfrac{1-9}{2}\right)\\\\ pm=\left( \dfrac{3}{2}, \dfrac{-8}{2}\right)\\\\ \Large\boxed{pm=\left( \dfrac{3}{2},-4\right) }$
