# 87 DOWN ON THE FARM
Colleen recently purchased a farm that raises chickens. Since she has never raised chickens before, Colleen wants to
learn as much about her baby chicks as possible. In particular, she wants to know how much a baby chick weighs
when it is hatched.
To find out, Colleen decided to track the weight of one of the chicks that was born just before she purchased the
farm. She found that her chick grew steadily by about 5.2 grams each day, and she assumes that it has been doing
so since it hatched. Nine days after it hatched, the chick weighed 98.4 grams.
a) What is the baby chick's rate of growth? That is, how fast does the baby chick grow each day? How does this rate
relate to the equation of the line?
b) Before graphing, describe the line that represents the growth of the chick. Do you know any points on the
line? Does the line point upward or downward? How steep is it?
