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!
