Write the equation for the Phillips curve (PC) with anchored expectations. Use output instead of the unemployment rate

Now suppose that the economy begins with Y = Y and inflation equal to the central bank's target, a. Assume that central bank policy is to chosen the real interest rate, which is safely above its lower bound throughout this problem (Ill).
