It is the last one.

Step-by-step explanation:

You must factor out the top expression, and then factor the bottom expression. Then, cancel out all of the terms that are equivalent to get one expression on the left side of the inequality sign. Then, subtract the answers to the "0" side and divide to find the coordinates.
