勾配 (-1/5 , 1/3),(4/5 ,-5/3)

解

勾配

(- \frac{1}{5}, \frac{1}{3}), (\frac{4}{5}, - \frac{5}{3})

解

m = - 2

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}) = (- \frac{1}{5}, \frac{1}{3}), (x_{2}, y_{2}) = (\frac{4}{5}, - \frac{5}{3})

m = \frac{- \frac{5}{3} - \frac{1}{3}}{\frac{4}{5} - ( - \frac{1}{5} )}

改良

m = - 2
