Extracted text: 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 în 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 %3D 2. A biologist wants to study the relationship between the number of trees x per acre and the number of birds y per acre. She came up with the equation of the regression line
