中間点 (-7/3 , 1/3),(-5/3 ,-7/3)

解

中間点

(- \frac{7}{3}, \frac{1}{3}), (- \frac{5}{3}, - \frac{7}{3})

(- 2, - 1)

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{7}{3}, \frac{1}{3}), (x_{2}, y_{2}) = (- \frac{5}{3}, - \frac{7}{3})

= (\frac{- \frac{5}{3} - \frac{7}{3}}{2}, \frac{- \frac{7}{3} + \frac{1}{3}}{2})

改良

= (- 2, - 1)
