Part a: the approximate y-intercept of the line of best fit is (0, 4). it represents the number of matches a student might win with 0 months of practicing boxing.part b: a graphing calculator computes the line of best fit as    y = 1.63636x + 4all the given points are used in the calculation.when x=13, this gives      y = 1.63636*13 + 4 ≈ 25.27the number of matches that could be won after 13 months of practice is 25.
