Use the paragraph below to answer question 1 &2
Most chickens reach maturity and begins laying eggs at around 20 weeks of age. From this point forward, however, as the chicken ages, its egg production decreases. A farmer was given a flock of 100 chickens (all of which were the same age) and asked to measure daily egg output for the entire flock at random intervals starting at maturity until the chickens were 70 weeks old. The data are recorded in the scatterplot below, and the line of the best fit has been drawn.
