Your shows possession
Use your before a noun to show that something belongs to or relates to the person being addressed. Example: “Your answer is clear.”
You're means you are
You're is a contraction of you are. Example: “You're correct” means “You are correct.”
Expand the contraction
When unsure, replace you're with you are. If the sentence still works, you're is likely correct. If the sentence shows ownership, use your.
