What is the line drawn on a production possibilities graph called?

Hello! My name is Zalgo and I am here to help you out today. The name of the said "line" is called the "Production Possibilities Frontier". it is mostly used in business analysis (for example, how much something has been sold for over a month).

I hope that this helps! :P
