tangent of y=(5x)/(x-3),(4,20)

tangent of

y = \frac{5 x}{x - 3}, (4, 20)

y = - 15 x + 80

Solution steps

Find the slope of

y = \frac{5 x}{x - 3} : \frac{d y}{d x} = - \frac{15}{( x - 3 ) ^{2}}

Compute the slope of

y = \frac{5 x}{x - 3}

(4, 20) : m = - 15

Find the line with slope m=

- 15

and passing through

(4, 20) : y = - 15 x + 80

y = - 15 x + 80

y = \frac{x + 1}{x - 1}

f = e

x e^{x^{2}}

f (x) = x^{3}

2 sin (x)
