slopeintercept (1,1),(3,-5/6)

解答

斜率截距

(1, 1), (3, - \frac{5}{6})

y = - \frac{11}{12} x + \frac{23}{12}

求解步骤

计算斜率

(1, 1), (3, - \frac{5}{6}) : m = - \frac{11}{12}

计算

y

轴截距:

b = \frac{23}{12}

构建直线方程

y = mx + b

其中

m = - \frac{11}{12}

且

b = \frac{23}{12}

y = - \frac{11}{12} x + \frac{23}{12}

\int sin (3 x) sin (8 x) d x

\int sin (4 x + 1) d x

\frac{\partial}{\partial y} (sin (y) sin (x))

a re a x + y^{2} = 12, x + y = 0

\int \frac{1}{t ^{2} - 4 t + 29} d t
