perpendicular y=-4x-9,(0,3)

perpendicular

y = - 4 x - 9, (0, 3)

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

Solution steps

Find the line

y = mx + b

perpendicular to

y = - 4 x - 9

that passes through

(0, 3)

Find the slope of

y = - 4 x - 9 : m = - 4

Compute the slope of the perpendicular line:

m_{p} = \frac{1}{4}

Find the line with slope m=

\frac{1}{4}

and passing through

(0, 3) : y = \frac{1}{4} x + 3

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

y = - 5 x - 1

x^{3} - 6

f (x) = x^{3} - x^{2} - x + 1

f (x) = \frac{x ^{2}}{1 + x}

f (x) = 3 (x + 2)^{2} - 7
