Calculate the slope and y-intercept of the ff. 1. A study was done to investigate the relationship between the age in years of a young person x and the time y in minutes at which the child can run one mile. Data from children between the ages of 8 and 15 was collected. The equation of the regression line was found to be y = 17 - 0.5x
