勾配 (-2/7 , 2/3),(5/7 ,-7/3)

解

勾配

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

解

m = - 3

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

m = \frac{- \frac{7}{3} - \frac{2}{3}}{\frac{5}{7} - ( - \frac{2}{7} )}

改良

m = - 3

\frac{d}{d x} (5 e^{x} + 3)

derivative of (x^2+4e^{-2x})

\frac{d}{d x} ((x^{2} + 4) e^{- 2 x})

(x^2-1)((dy)/(dx))=2y

(x^{2} - 1) (\frac{d y}{d x}) = 2 y
