Part A: What is the approximate y-intercept of the line of best fit and what does it represent? (5 points)
Part B: Write the equation for the line of best fit in the slope-intercept form and use it to predict the number of matches that could
be won after 13 months of practice. Show your work and include the points used to calculate the slope. (5 points)
