perpendicular x-4y=20,(-2,4)

perpendicular

x - 4 y = 20, (- 2, 4)

y = - 4 x - 4

Solution steps

Find the line

y = mx + b

perpendicular to

x - 4 y = 20

that passes through

(- 2, 4)

Find the slope of

x - 4 y = 20 : m = \frac{1}{4}

Compute the slope of the perpendicular line:

m_{p} = - 4

Find the line with slope m=

- 4

and passing through

(- 2, 4) : y = - 4 x - 4

y = - 4 x - 4

f (x) = \frac{( x + 8 )}{x - 8}

(x + 5)^{2}

f (x) = \frac{60 t}{t ^{2} + 36}

f (x) = \frac{3}{x} + 9

f (x) = - x^{5} - 3 x^{4} + 2 x^{2}
