Every boxer puppy in a litter is weighed each day. The scatter plot shows the age and mass recorded at each weighing.

The line of best fit has the equation y=a+bx, where a and b are constants. What does the y-intercept tell you about the puppies in the litter?

• The predicted change in mass of a puppy each day.

• The predicted mass of a puppy at birth.

• The number of puppies born on day 0.

• The mass of the entire litter of puppies.

Each puppy in a litter is weighed each day. The scatter plot shows the age and mass recorded at each weighing.

The line of best fit is shown on the scatter plot. What does the slope of the line tell you about the puppies in the litter?

• The predicted change in mass of a puppy each day.

• The predicted mass of a puppy at birth.

• The number of puppies born on day 0.

• The mass of the entire litter of puppies.

This scattered plot shows the relationship between the average weight and average heart rate for 11 different animals.

The line of best fit is shown on the graph.

Select all TRUE statements based on the graph.

• The line of best fit provides a good estimate of an animal's average heart rate based on its weight for all animals.

• The y-intercept is at approximately (0,185).

• Point D is an outlier because it is far away from the other data points.  

What is the ordered pair that represents the outlier in the data?

Using the line of best fit or trend line, predict the number of umbrellas used in 9 rainy days.
