A geologist recorded the temperate of the top soil and sub soil in a specific area. The top soil was 5 inches under the ground with a temperature of 78 degrees. The sub soil was 24 inches under the ground with a temperature of 89 degrees. Which calculation could be used to determine the rate of change?

• Subtract 89 from 78

• Subtract 24 from 5

• Find the slope between (0,0) and (5,78)

• Find the slope between (5,78) and (24,89)
