perpendicular y=-2x-4

perpendicular

y = - 2 x - 4

y = \frac{1}{2} x + b

Solution steps

Find the slope of

y = - 2 x - 4 : m = - 2

Compute the slope of the perpendicular line:

m_{p} = \frac{1}{2}

Line with slope m=

\frac{1}{2} : y = \frac{1}{2} x + b

y = \frac{1}{2} x + b

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

x^{2} + 2 x + 1

f (x) = \frac{x + 3}{x + 6}

f (x) = 7 x
