Answer:

C. y = x - 4

Explanation:

We notice that values of x are consistently 4 more than the corresponding values of y. One way this can be written is ...

x = y + 4 . . . (matches choice D)

However, we usually consider y to be the dependent variable. Rearranging this to "y = " form, we have ...

y = x - 4 . . . matches choice C
