Our ice machine is making ice in preparation for the game that starts at 7:00 P.M. The machine is monitored, and the amount of ice is recorded at the end of each hour. The results are in the table below. 3:00 P.M 1:00 P.M. 2:00 P.M. Time 12:00 P.M. Pounds 368 436 504 300 of ice (a) Show that the data are linear. the difference from 1:00 P.M. to The difference in pounds of ice from 12:00 P.M. to 1:00 P.M. is 68 T and the difference from 2:00 P.M. to 3:00 P.M. is 68 . Because these 2:00 P.M. is 68 the function is linear. values are all the same (b) Let t denote the time in hours since noon, and let I denote the pounds of ice made. Find a linear model for I as a function of t. I =
