No, because it has a constant rate of change.
No, because it does not have a constant rate of change.

Answer 1

B. Yes, because it does not have a constant rate of change.

Explanation:

For a function to be a function (or linear), the rate of change MUST be proportional. In this data set, the numbers do not seem proportional, which makes it non-linear.
