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 (42,9) . Round the slope to the nearest hundredth.
The slope of the linear model represents the change in the average weight of dogs in pounds as the age in months increases by one.
In this case, the slope would be (9-0)/(42-0) = 9/42 ≈ 0.21 (rounded to the nearest hundredth).
The y-intercept (0,0) means that at 0 months, the average weight of dogs is 0 pounds.
