斜率 2x+5y+20=0

解答

斜率

2 x + 5 y + 20 = 0

m = - \frac{2}{5}

求解步骤

转换为标准形式:

2 x + 5 y = - 20

斜率标准形式:

m = - \frac{2}{5}

m = - \frac{2}{5}

d o main f (x) = \frac{x ^{2} + 5 x - 6}{x ^{2} - 5 x - 6}

r an g e \frac{- 2 - 5 x}{3 x - 1}

cr i t i c a l f (x) = - \frac{1}{x ^{2} + 7}

d o main f (x) = \frac{t}{t + 1}

d o main 6 (x + 1)^{2} - 5 (x + 1) - 1
