What does the Phillips Curve illustrate about the relationship between the unemployment rate and inflation?

The Phillips Curve shows a relationship between unemployment and inflation, suggesting that when unemployment is low, inflation tends to be high, and vice versa. This happens because when more people have jobs, they spend more money, which can drive prices up. Conversely, when unemployment is high, there are fewer people spending money, leading to lower inflation. For example, during a strong economy where many people are employed, prices for goods and services may rise quickly. This relationship helps economists understand how job markets and prices interact, although it can change over time due to various factors.
