Bob decides that after his heart attack is a
good time to get in shape, so he starts exer-
cising each day and plans to increase his
exercise time as he goes along. Look at the
two line graphs shown in the following fig-
ures. One is a good representation of his
data, and the other should get as much use
as Bob's treadmill before his heart attack.
