6. Use the Phillips curve you obtained in 1. to answer the following question. What has been the natural rate of unemployment over this period? Round your answer to 2 decimal places. y = -1.0406x + 6.7864 / 1=-1.04 + 6.79% 7. Use the Phillips curve you obtained in 1. to answer the following question. Imagine the intercept of that Phillips curve changes and you know that after that change the natural rate of unemployment is 1 percentage point higher than the natural rate of unemployment you obtained in question 6. Calculate and provide the new intercept
