Answer:
option C
Explanation:
Given table is a linear function when the change in y to change is x is a constant.
From the tables, difference of x is a constant 1
Lets look at the difference of y values
First table
We find the change in y values


the difference is not a constant. So it is not a linear
Second table


the difference is not a constant. So it is not a linear
Third table



the difference is a constant. So it is a linear function.
