If f is a linear function such that f(x+2) - f(x) = 6, find the value of inverse of f (x+2) - inverse of f(x)

Only clue she gave us was f(x)= mx+b but I don't know how to utilize that information.

F(a)=2a F(b)=2b determine F(x)=mx+b Have Final Exam today Please Help

the answer is F(x)=2x,but I have no idea how to get there.Help would be greatly appreciated.Thanks
