中点 (3,sqrt(2)),(6,2)

解答

中点

(3, 2), (6, 2)

(\frac{9}{2}, \frac{2 + 1}{2})

求解步骤

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

的中点:

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

(x_{1}, y_{1}) = (3, 2), (x_{2}, y_{2}) = (6, 2)

= (\frac{6 + 3}{2}, \frac{2 + 2}{2})

整理后得

= (\frac{9}{2}, \frac{2 + 1}{2})

x^{3} - x y + y^{3} = 1

(17, - 11), (- 14, - 16)

(1, 1)

y = - x

y = 3 x - 2, (3, 7)
