Answer 1

The table of values that represents a linear function is table A.

This is because in a linear function, the change in y is directly proportional to the change in x. In table A, as x increases by 2, y increases by 1. And as x decreases by 2, y decreases by 1. This shows a constant rate of change and is characteristic of a linear function.
