9. The Phillips curve in the late 20th century The following table presents historical unemployment and inflation data in the United States for the years 1974 through 1978. Unemployment Rate Inflation Rate Year (Percent) (Percent) 1974 5.6 11.0 1975 8.5 9.1 1976 7.7 5.8 1977 7.1 6.5 1978 6.1 7.6 Plot the data for these five years on the following graph.Plot the data for these five years on the following graph. Note: You will not be graded on how you plot the points, but plotting the points accurately on the graph will help you examine the relationship between unemployment and inflation during this period and solve the problems that follow.
