Swap partition not working

edit

Hello! I think my swap partition is not enabled. I did some search in DuckDuckGo to understand how to enable it but I'm not confident with the process because I don't know for sure if the information I read applies to my case. How do I make the swap partition works? I'm using Fedora 29. Thank you in advance.

Here is some log info:
