Rachel found the following rate of change for the scenario represented in this table. A 2-column table with 5 rows. Column 1 is labeled Time (hours) with entries 4, 5, 6, 7, 8. Column 2 is labeled Berries picked with entries 128, 181, 234, 287, 340.

What can you conclude from her work?
Check all that apply.
The scenario is represented by a linear function, since the rate of change is constant.
The scenario is represented by a nonlinear function, since the rate of change is constant.
The berries are picked at a constant rate of 53 per hour.
The berries are not picked at a constant rate.
