What is the temperature after 4 hours?
16 degrees
Determine the rate of change. (slope)
4/2 = 2
Write a linear equation that models the relationship between the temperature and the time.
y = 2x + 8
Does this graph represent a function? Why or why not?
Yes, because each hour (input) is assigned to exactly one temperature in degree (output).
Explain what the data point (6,20) means in the context of the problem
After 6 hours the temperature is 20 degrees fahrenheit.
Explain what the rate of change means in the context of the problem.
Every 2 hours the temperature rises 4 degrees.
