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). The graph shows his results for the first motor oil. The Table shows his results
for the second motor oil. Which statement is true?
