Does anyone have any advice on how to work this math problem?

Given: f(f(x))=4x+9. Find the positive slope of f(x), given that f(x) is a linear functionDoes anyone have any advice on how to work this math problem?
the slope would be 4 for this, because it's coming from the equation y=mx+b, where m is the slope. so it's four.
