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

The Phillips Curve shows the relationship between unemployment and inflation, suggesting that when unemployment is low, inflation tends to be high, and when unemployment is high, inflation tends to be low. This happens because when more people have jobs, they have more money to spend, which can drive prices up. For example, if a lot of people are employed and buying new cars, car prices may rise due to the increased demand. Conversely, if many people are unemployed, there is less spending, leading to lower prices and inflation. This curve helps economists understand how changes in the job market can affect prices in the economy.
