perpendicular y= 1/4 x-3

perpendicular

y = \frac{1}{4} x - 3

y = - 4 x + b

Solution steps

Find the slope of

y = \frac{1}{4} x - 3 : m = \frac{1}{4}

Compute the slope of the perpendicular line:

m_{p} = - 4

Line with slope m=

- 4 : y = - 4 x + b

y = - 4 x + b

x + y = 3

(- 2, 7.7), (3, - 2.3)

f (x) = 1 - 4 - x^{2}

f (x) = x^{4} - 128 x^{2} + 4096

f (x) = \frac{x ^{2} - 12 x + 35}{x - 5}
