平行线 4x+6y=-84

解答

平行线

4 x + 6 y = - 84

y = - \frac{2}{3} x + b

求解步骤

计算

4 x + 6 y = - 84

的斜率:

m = - \frac{2}{3}

斜率 m=

- \frac{2}{3}

的直线:

y = - \frac{2}{3} x + b

y = - \frac{2}{3} x + b

in f l ec t i o n f (x) = x 25 - x^{2}

d o main f (x) = 4 - ∣ x ∣

d o main x + 9 - x

in v erse f (x) = - \frac{5}{4 - x}

cr i t i c a l y = (x - 3)^{3}
