中間点 (9,-6),(6,-9)

解

中間点

(9, - 6), (6, - 9)

(\frac{15}{2}, - \frac{15}{2})

解答ステップ

(x_{1}, y_{1}), (x_{2}, y_{2})

の中間点:

(\frac{x _{2} + x _{1}}{2}, \frac{y _{2} + y _{1}}{2})

(x_{1}, y_{1}) = (9, - 6), (x_{2}, y_{2}) = (6, - 9)

= (\frac{6 + 9}{2}, \frac{- 9 - 6}{2})

改良

= (\frac{15}{2}, - \frac{15}{2})
