This is not a linear function, since the average rate of change is not constant. 28. is a linear function with slope = 4, since the average rate of change is constant at 4. 31. This is a linear function with slope = since –3, the average rate of change is constant at –3. This is not a linear function, since the average 2 2 rate of change is not constant. This is not a linear function since the average rate of change is not constant.
