Determine as coordenadas do ponto médio de A (4,2) e B (2,4).

\boxed{x_{M}= \frac{x_{A}+ x_{B}}{2},\frac{y_{A}+ y_{B}}{2}}\\ \\\\ \boxed{x_{M}=\frac{4+2}{2}=3 } \\ \\ \\ \boxed{y_{M}=\frac{2+4}{2} = 3 }

Xm= Xa+Xb/2
Xm=4+2/2
Xm=6/2
Xm=3


Ym=Ya+Yb/2
Ym=2+4/2
Ym=6/2
Ym=3

As coordenadas do ponto médio citado são { 3 , 3}
