and the other one: 14.  Carnell is finding the equation of a median-median line. He found that the equation of the line through the first and third summary points is y = 3.5x + 72. Then he found that the equation of the line that is parallel to this line and passes through the second summary point is y = 3.5x + 54. What is the equation of the median-median line?
