Answer:
Step-by-step explanation:
I suspect a typo, since is not a straight line. Let's go with
That means the slope is -4/5
Any line perpendicular to it will have slope 5/4
Since both lines pass through (0,6), our second line is
(x) =
let y = f(x), then rearrange making x the subject
y = ( multiply both sides by (x - 2 ))
y(x - 2 ) = 3x (distribute )
xy - 2y = 3x ( subtract 3x and add 2y to both sides )
xy - 3x = 2y (factor out x on left side )
x(y - 3 ) = 2y ( divide both sides by (y - 3) )
x =
change y to x for inverse function
(x) =
