the temperature of a cup of water is a linear function of the time that is in the microwave. The temperature at 0 seconds is 60 F and the temperature at 120 seconds is 200 F.

A) Express the linear function in the form t = ms + b where t is the Fahrenheit temperature and s is the time in seconds.  {hint: write the equation of the line through (0,60) and (120,200)}

B) Use the linear function to determine the temperature at 30 seconds

c) graph the linear function
