A mechanic is comparing how quickly two kinds of motor oil heat up. He records the change in the temperature (degrees Fahrenheit) of each motor oil over time (minutes) in the same car traveling under the same conditions at the same speed. The graph shows his results for the first motor oil.
The table shows his results for the second motor oil.

What conclusion can the mechanic make about the two kinds of motor oil?
A
The rate of temperature increase for the first motor oil is 0.5°F greater than that of the second motor oil.
B
The rate of temperature increase for the first motor oil is 3°F greater than that of the second motor oil.
C
The rate of temperature increase for the second motor oil is 3°F greater than that of the first motor oil.
D
The rate of temperature increase for the second motor oil is 0.5°F greater than that of the first motor oil.
