Jeff drew a line through (0, 0) and (7, 7) and said it was the line of best fit for the data. Part A: Explain why Jeff's line is NOT the best fit.
Part B: What would be a better line of best fit for the scatter plot?
Part C: How does the actual line of best fit compare with Jeff's line?

Aball is thrown from a height of 139 feet with an initial downward velocity of 15 ft/s. the ball's height h (in feet) after t seconds is given by the following. h=139-15t-16t^2 how long after the ball is thrown does it hit the ground? round your answer(s) to the nearest hundredth. (if there is more than one answer, use the "or" button.) t =
