What are the coordinates of the missing vertex?

For the first attachment, the missing vertex is (-2,6). I got this by going up the graph from point W 5 times. For the second attachment, the missing vertex is (4,-5). I got this because I used point M and went right. When my mouse was at the point that looks like a square, the point was at (4,-5). Hope this helps you!
