The macroeconomic curve depicting an inverse short-run trade-off between inflation and unemployment is known as:

The Phillips Curve, named after economist A.W. Phillips (1958), depicts the inverse short-run relationship between inflation and unemployment  when unemployment falls, wages and inflation tend to rise, and vice versa. It became a key tool for macroeconomic policymaking. The Laffer Curve shows tax revenue vs. tax rate; the Kuznets Curve shows inequality vs. income; the Beveridge Curve shows job vacancies vs. unemployment; the Lorenz Curve shows income inequality. None of these describe the inflation-unemployment trade-off.
