perpendicular y-4= 9/8 (x-9),(5,5)

perpendicular

y - 4 = \frac{9}{8} (x - 9), (5, 5)

y = - \frac{8}{9} x + \frac{85}{9}

Solution steps

Find the line

y = mx + b

perpendicular to

y - 4 = \frac{9}{8} (x - 9)

that passes through

(5, 5)

Find the slope of

y - 4 = \frac{9}{8} (x - 9) : m = \frac{9}{8}

Compute the slope of the perpendicular line:

m_{p} = - \frac{8}{9}

Find the line with slope m=

- \frac{8}{9}

and passing through

(5, 5) : y = - \frac{8}{9} x + \frac{85}{9}

y = - \frac{8}{9} x + \frac{85}{9}

f (x) = x (x - 1)^{\frac{2}{5}}

f (x) = (x + 3)^{3}

(2, - 3), (9, 21)

f (x) = - tan (x - \frac{4 π}{3})

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