Answer

Brief Explanations:

  1. For the y - intercept: In a linear model representing the relationship between age (x - variable) and mass (y - variable) of puppies, when x = 0 (at birth), the y - value of the line of best - fit gives the predicted mass of a puppy at birth.
  2. For the slope: The slope of a line in a linear relationship between two variables represents the rate of change. Here, as the x - variable is age (in days) and the y - variable is mass, the slope represents the predicted change in mass of a puppy each day.

Answer:

  1. The predicted mass of a puppy at birth
  2. The predicted change in mass of a puppy each day
