The correct interpretation is: Every month, a dog averages a gain of 0.21 pounds and weighs 0 pounds at birth.
The slope of the linear model is 0.21, which means that for every month increase in age, a dog's weight increases by 0.21 pounds on average. The y-intercept (0,0) indicates that a dog weighs 0 pounds at birth.
Therefore, when using the ordered pair (9,42), it means that on average, a 9-month-old dog would weigh approximately 42 pounds according to this linear model.
A veterinarian collected data on the average weight of dogs by age in months. Interpret the slope and the y-intercept (0,0) of the linear model, using the ordered pair (9,42). Round the slope to the nearest hundredth.
