Delete a shape in Writer

I have searched for an answer using every key word I can think of before I posted this.
The question:
In a writer document, I created a table. I copied and pasted an image in the table. I clicked on Insert > Shape and used the free form line tool to draw a line. I want to delete the line. How do I delete the line?

You seem to be out of luck everytime you search for something. Hint 1: Navigator. Hint 2: mark with mouse pointer, hit DEL.

In addition to @Cookievore: If you have placed the drawn line in the background, you can also select the button “Select” in the toolbar “Drawing” and then mark and remove the line.
