a linear function has a constant additive rate of change, while a nonlinear function does not. for a table of values to be linear, the dependent variable must have a constant rate of change as the independent variable increases by 1. on a graph, the function must be a straight line to be linear.

total change in temperatures = -28°f

total time taken for the change = 4hrs

temperatures change per hour = -28°f ÷ 4hrs = -7°f/hr

the temperatures drop by 7°f in every hour.
