Why is Linkedin on my Mac? I did not install it.

Delete what, the ability to connect to LinkedIn (just like the ability to connect to FaceBook or Gmail, or iCloud?) unless there is an account there is nothing to delete.

What about all these other ones

Do you want to delete them?

Deleting it isn't a problem. However, someone else did add that to your Mac's notifications. When you enter Internet Accounts in the System Preferences, you have to login to your LinkedIn account in order for the button to get entered into the left column.

It can't get there any other way.

There is no LinkedIn account.

Yes, there is. That's how the notification button got into the left column. Someone with a LinkedIn account supplied their account email and password to get it there.

Did you have a party or something a while back? Anyone there could have "borrowed" your Mac for a few moments to login. They may have wanted to see if any job inquiries had been responded to, or other activity.

Very simple check. Click on the LinkedIn button. Who's email address does it say it belongs to (where I've circled my blanked out address):

Anyone's email address you recognize?

It's still the correct answer. Someone used your computer to visit LinkedIn and set up an account. It doesn't need to be in your browser at all times, or have been added as a bookmark to be true. Whoever it is also went through LinkedIn's steps to set up notifications:

Apple's OS X Mavericks allows you to receive LinkedIn notifications, access your LinkedIn connections, view shared links, and share updates directly from your desktop. Note: LinkedIn integration is not supported for previous versions of OS X.

To enable LinkedIn features in OS X Mavericks:

1. Go to your Mac's System Preferences and select Internet Accounts.
2. Select LinkedIn from the list of services on the right.
3. Enter your LinkedIn email address and password, then click Sign In.

• Find your LinkedIn Connections in OS X contacts
• Share Updates from Safari and Notification Center
• View Shared Links in Safari
• Receive LinkedIn notifications in Notification Center
• Upload a profile picture from Photo Booth

Yes, I understand you didn't set it up, but someone did. It can't get there by itself. And as the steps from LinkedIn show, the only way to even get the Notifications set up is to have a LinkedIn account, since it requires logging in to the account to get the Notifications banner in the settings.

It would have taken a person only a few minutes to do this if they already had a LinkedIn account. Closer to 15 is they were setting up an account from scratch. Why someone would bother to take the time to do that on your Mac, I can't guess.

I have a LinkedIn account and don't have Notifications setup for it because I don't feel I need it, and it needs to be done manually. Yosemite won't put it there on its own. But heck, for all I know, I may have removed an automatically added Notification button for LinkedIn months ago and just don't recall doing it.

And every version since, it's as integrated as iCloud, or Facebook, or Google are, in other words not at all until a user supplies account credentials.

That's not what Kurt said, they initiate syncing when and only if someone supplies valid account credentials in the login box, visiting the website will not do that.

Is this your LinkedIn account, yes or no. If no whose account is it?

LinkedIn is a website that is mostly meant for business to business contacts. Sounds like someone in your household signed up with an account and used your email address as the email recipient.

That's impossible because I am the only user of this machine and I did not set it up.

Whose LinkedIn account is it, do you have one or does this count belong to a stranger?
