Sharepoint List, How can i remove an item from the list?

I'm new to the SharePoint fiasco, I see there is a list with 22 records I need to remove one of those. I have gone to site setting and locate the list. open the list and click on the tittle bar and see where Items and List heading shows at the top. Under Items I see the edit item and Delete Item but they are gray out. What do I need to do, go, click in order to delete one item of the list?
