Which curve illustrates the short-run relationship between inflation and unemployment?

The short-run relationship between inflation and unemployment is captured by the Phillips Curve. It describes an inverse trade-off: when unemployment is low, inflation tends to rise, and when unemployment is high, inflation tends to fall. This happens because strong demand and tight labor markets push wages up and, as firms pass higher costs to prices, the overall price level increases. In the short run, wages and prices don’t adjust instantly (they’re sticky), so changes in demand show up as moves in both inflation and unemployment instead of in just one variable. The other curves don’t depict this specific inflation–unemployment relationship. The Laffer Curve shows tax revenue as a function of tax rate, not inflation or unemployment. The Aggregate Demand Curve maps the relationship between the overall price level and the quantity of goods demanded, not the trade-off between inflation and unemployment. The Production Possibility Frontier illustrates the trade-off between producing two goods given resources, not macroeconomic inflation or unemployment.
