perpendicular y=-1/2 x+8,(-2,5)

perpendicular

y = - \frac{1}{2} x + 8, (- 2, 5)

y = 2 x + 9

Solution steps

Find the line

y = mx + b

perpendicular to

y = - \frac{1}{2} x + 8

that passes through

(- 2, 5)

Find the slope of

y = - \frac{1}{2} x + 8 : m = - \frac{1}{2}

Compute the slope of the perpendicular line:

m_{p} = 2

Find the line with slope m=

2

and passing through

(- 2, 5) : y = 2 x + 9

y = 2 x + 9

\frac{2 x ^{2} - 3 x - 20}{x - 5}

6 x - y = - 12, (0, 0)

(- 2, - 1), (- 2, 4)

x

f (x) = (\frac{1}{x}) + 4

What is the perpendicular y=-1/2 x+8,(-2,5) ?
The perpendicular y=-1/2 x+8,(-2,5) is y=2x+9
