What is the slope of the regression equation? What does it mean? The slope of the regression equation is 0.947 and it means that per capita income by Number for each year. increases е. Use the line of best fit to estimate PCINC for 1900, and for 2000. Round your answers to the nearest integer (dollar). When the year is 1900, y 783 When the year is 2000, y 2447
