Answer:

(a) The set must have a constant additive rate of change

Explanation:

If a linear function is suitable for representing the data, the data will demonstrate a constant slope. That is, for evenly spaced values of the independent variable, the differences of the values of the dependent variable will be constant. We can say ...

The set must have a constant additive rate of change.
