perpendicular y= 1/5 x-7

perpendicular

y = \frac{1}{5} x - 7

y = - 5 x + b

Solution steps

Find the slope of

y = \frac{1}{5} x - 7 : m = \frac{1}{5}

Compute the slope of the perpendicular line:

m_{p} = - 5

Line with slope m=

- 5 : y = - 5 x + b

y = - 5 x + b

in t erce pt s f (x) = y - 4 = 7 (x - 6)

s l o p e in t erce pt - 8

d o main f (x) = \frac{x}{x + 3}

d i s t an ce (9, - 10), (9, 20)

e x t re m e f (x) = x 100 - x^{2}
