Answer:
(b) see below
Explanation:
These tables all have x-values that are consecutive integers, including 0.
The equation has an x-coefficient of -1/2, so as x increases by 1, y should decrease by 1/2 from one row of the table to the next. This is only the case for table B.
__
As another check, the y-value for x=0 is the constant in the equation, -1. That is not the case for table C, further evidence that C is incorrect.
