For this case, the first thing we must do is define variables. We have then: h: number of hours t: temperature We now write the equation that represents the problem. We have then: t (h) = -2h + 32 We note that for h = 0 t (0) = -2 (0) + 32 t (0) = 32 Answer: An equation that represents the temperature, t, at your h is: t (h) = -2h + 32
