Slope of inverse? Check

[aisha]

:smile: My question says f(x)=(-5/7)x-3 determine the slope of f^-1(x) without finding the inverse. I think the answer is the slope of f^-1(x)=(-7/5)x
Is this correct?

[phreak]

Yes. It is correct. Once again, you can check this by graphing the function and seeing the reflection over f(x) = x

I actually had the same question, where did the -3 go?

MaryB, the -3 has nothing to do with the slope.
