中間点 (-17/8 ,-19/6),(25/6 , 3/2)

解

中間点

(- \frac{17}{8}, - \frac{19}{6}), (\frac{25}{6}, \frac{3}{2})

(\frac{49}{48}, - \frac{5}{6})

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}) = (- \frac{17}{8}, - \frac{19}{6}), (x_{2}, y_{2}) = (\frac{25}{6}, \frac{3}{2})

= (\frac{\frac{25}{6} - \frac{17}{8}}{2}, \frac{\frac{3}{2} - \frac{19}{6}}{2})

改良

= (\frac{49}{48}, - \frac{5}{6})
