perpendicular y= 1/4 x+1,(-2,1)

perpendicular

y = \frac{1}{4} x + 1, (- 2, 1)

y = - 4 x - 7

Solution steps

Find the line

y = mx + b

perpendicular to

y = \frac{1}{4} x + 1

that passes through

(- 2, 1)

Find the slope of

y = \frac{1}{4} x + 1 : 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, 1) : y = - 4 x - 7

y = - 4 x - 7

\frac{x - 2}{x - 4}

(0, 7), (7, 3)

x + \frac{1}{x}

f (x) = \frac{- 2 x + 15}{x ^{2} + 5 x}

x + 2
