The scatterplot shows data set A, which consists of the weights y, in pounds, of a Labrador retriever puppy at various ages, x, in months. The equation of a line of best fit for the relationship in data set A can be written as \( y=-5.1+8.7x \) , where \( 2\le x\le6 \).
The puppy was weighed again at 9 months old and weighed 52 pounds. Data set B consists of all the data points in data set A as well as the data point (9, 52). The equation of a line of best fit for data set B can be written as \( y=r+sx \), where r and s are constants and \( 2\le x\le9 \).
