勾配 (8 1/7 ,9),(4,3 1/5)

解

勾配

(8 \frac{1}{7}, 9), (4, 3 \frac{1}{5})

解

m = - \frac{147}{50}

解答ステップ

2点間の傾斜: 傾斜

= \frac{y _{2} - y _{1}}{x _{2} - x _{1}}

(x_{1}, y_{1}) = (8 \frac{1}{7}, 9), (x_{2}, y_{2}) = (4, 3 \frac{1}{5})

m = \frac{3 \cdot \frac{1}{5} - 9}{4 - 8 \cdot \frac{1}{7}}

改良

m = - \frac{147}{50}
