##### 1 Answer

Choice D works.

#### Explanation:

The table you have with

I looked first at the ordered pair

Any of the others would give you

Another easy point to look at is

For B. we get:

Equation C:

Try D:

So we don't need to try any other coordinate pairs; all of them should work, and these two don't work in equations A,B, or C.

I hope that helps!
