Question

Ponto médio do segmento Pq e m(-2,4) se p(2,2) as coordenadas de Q são?

Answer 1

Xm = $\frac{Xq + Xp}{2}$
- 2 = $\frac{Xq + 2}{2}$
- 2.2 = Xq + 2
- 4 = Xq + 2
- 4 -2 = Xq
Xq = - 6
------------------------------------------
Ym = $\frac{Yq + Yp}{2}$
4 = $\frac{Yq + 2}{2}$
4.2 = Yq + 2
8 = Yq + 2
8 - 2 = Yq
Yq = 6
-----------------------------------------
Q = (- 6, 6)
