Decribe the MP curve

The MP-curve (‘monetary policy’) gives all combinations of real interest rates r and incomes Y at which the money market is in equilibrium

Why is MP upward sloping

To see why the  MP  curve has an upward slope, we need to recognize that central banks seek to keep inflation stable. To stabilize inflation, monetary policymakers follow the  Taylor principle,  named after John Taylor of Stanford University, in which they raise  nominal  rates by more than any rise in expected inflation so that  real  interest rates rise when there is a rise in inflation, as the  MP  curve suggests

Explain the downward sloping of the ad curve

Higher inflation is thus associated with lower output, which results in a downward-sloping AD-curve,
