How do I delete a news feed from fb on my Lumia 635, please?

[Windows Central Question]

I am a Senior and also a "newbie" enjoy my new phone, however having trouble getting rid of news feeds I don't wish to see. Also, some news feeds from close friends/relatives, I only see once and they are gone, then I see lots of news feeds over and over from others who have "liked" something on their phones.
