Question

what is the inverse function of y = -3x + 8

Answer 1

Answer:

The inverse is -1/3 ( x-8)

Step-by-step explanation:

y = -3x + 8

Exchange x and y

x = -3y+8

Solve for y

Subtract 8 from each side

x-8 = -3y+8-8

x-8 =-3y

Divide by -3

-1/3(x-8) = -3y/-3

-1/3(x-8) =y

The inverse is -1/3 ( x-8)
