Answer:
Explanation:
A linear function will result in a straight line. Thus, the difference between each x coordinate will be the same and the difference between each y coordinate will be the same.
For example, in Table A, the difference for each X coordinate is 2 (9-7. 7-5, etc...).
However, the difference between the Y coordinates is -2 until you reach the last one where 1-0 is -1 so it is not linear.
Applying this to the other tables shows the linear function in Table C.
