Find and equation for the inverse relation:
y=4x+8

To find the inverse equation, it is x = 4y + 8. However, people don't write it that form because they want the equation to look like this: y = mx + b.
Thus, you have to subtract 8 on both sides.
x - 8 = 4y + 8 - 8
x - 8 = 4y
x/4 - 2 = y
Let x divide by 4. Let 8 divide by 4. I hope this helps.
The previous answers don't even answer the question. The question demands the INVERSE, not the solution.

y = 4x+8
To get inverses, you switch the y with the x and vice versa
x = 4y + 8
4y = x - 8
y = (1/4)x - 2

Let's see- - -ah well, not me since I cannot do the math. But you flubbed too! The word is WHO'S. Missing an apostrophe.

do you mean like:
4y=16x+32
or
y=1/4x+1/8
