perpendicular y= x/4-4,(-8,5)

perpendicular

y = \frac{x}{4} - 4, (- 8, 5)

y = - 4 x - 27

Solution steps

Find the line

y = mx + b

perpendicular to

y = \frac{x}{4} - 4

that passes through

(- 8, 5)

Find the slope of

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

Compute the slope of the perpendicular line:

m_{p} = - 4

Find the line with slope m=

- 4

and passing through

(- 8, 5) : y = - 4 x - 27

y = - 4 x - 27

2 x + 7 y = 13

2 y - 4 x = 8

\frac{x ^{2} + 5 x + 4}{x ^{2} + 3 x + 2}

∣ x ∣ + 1

f (x) = 3 x^{2} - x - 3

What is the perpendicular y= x/4-4,(-8,5) ?
The perpendicular y= x/4-4,(-8,5) is y=-4x-27
