Hello, friends. I've recently started the finned x wing on sudoku coach and I'm having trouble finding the kill zone for it. Is it just the 9 in column 4, row 7 or can I eliminate column 4, row 8 as well? Thank you!

Hello, friends. I'm new to the swordfish, and I'm having trouble understanding which digits can be eliminated. Is it every four in the same column? If anyone can help me, I'd really appreciate it. Thank you
