A veterinarian collected data on the association between age and mass of Boxer puppies. A line of best fit was computed. The equation for the line is: y = 17.5x + 480. Which BEST interprets the slope of the linear model?
a
Each additional day is associated with an additional 17.5 grams of mass.
b
The predicted mass of a Boxer puppy at birth.
c
Every 17.5 days is associated with an additional 480 grams of mass.
d
Each additional day is associated with an additional 480 grams of mass.
a
Each additional day is associated with an additional 17.5 grams of mass.

Consider the data shown on the graph:
The y-intercept represents the base price of $ for airfare from NYC..
The slope represents a cost of cents per mile traveled.
According to the equation given, someone who traveled 2000 miles from NYC would pay $ for their airfare
According to the equation given, someone who paid $500 for airfaire from NYC would have traveled miles.
If the base cost for airfare changed to $50 and the cost per mile is unchanged, the new equation would be

The y-intercept represents the base price of $ 30 for airfare from NYC.
The slope represents a cost of 0.50 cents per mile traveled.
According to the equation given, someone who traveled 2000 miles from NYC would pay $ 1,030 for their airfare.
According to the equation given, someone who paid $500 for airfaire from NYC would have traveled 940 miles.
If the base cost for airfare changed to $50 and the cost per mile is unchanged, the new equation would be y = 50 + 0.50x.
What does the rate of change represent in context of the data?
