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.

Every month, a dog averages a gain of 4.3 pounds and weighs 0 pounds at birth.
Every month, a dog averages a gain of 4.3 pounds and weighs 0 pounds at birth.
Every month, a dog averages a gain of 4.67 pounds
Every month, a dog averages a gain of 4.67 pounds
Every 4.67 months, a dog averages a gain of 1 pound and weighs 0 pounds at birth.
Every 4.67 months, a dog averages a gain of 1 pound and weighs 0 pounds at birth.
Every month, a dog averages a gain of 0.21 pounds and weighs 0 pounds at birth.
The slope of the linear model is 4.67, which means that on average, a dog gains 4.67 pounds every month.
The y-intercept of the linear model is (0,0), which indicates that a dog weighs 0 pounds at birth.
Therefore, the interpretation of the slope and the y-intercept using the ordered pair (9,42) is that at 9 months old, a dog would on average weigh 42 pounds, with the assumption that the dog was born weighing 0 pounds and gained 4.67 pounds each month.
