    So in 5 mins water went from 98 degrees to 86 degrees in 5 mins which is a change of 10 degrees per 5 mins: 10/5 = 2 degrees per min Because the water got cooler, we need a negative sign. Because we started at 96 degrees, we need a constant (y-intercept), to represent where we started: y= -2t + 96 y represents the temperature of the pasta at time t Does this make sense?
