At 12pm, the temperature was 57o f. by 5pm, the thermometer read 36o f. assuming a constant change in temperature, calculate and interpret the unit rate of change (slope).

Unit rate of change = -4.2°F/hour

Step-by-step explanation:

Assuming a constant rate of change, a relationship between the change of temperature as a function of time (in hours) can be described as follows:

There is a temperature drop from 12pm to 5pm, which explains the rate of change being negative. This rate means that at every hour that goes by, the temperature drops by 4.2 degrees.

found it xd it ok yt

what is the original number? you forgot to add it.
