Getting row information in Oracle

I am working on a query:

Get the item_id, order_id, price from the order_line table where the price for an individual item's order is greater than the average of all orders for the item.

Here is what I have so far to get the average for all of the items:

SELECT order_id, AVG(price) FROM order_line
GROUP BY order_id

What can I do from here to get all of the prices (and item ids) where the price is greater than the average for each value?

How about this.

select a.item_id, a.rder_id, a.price
from order_line a,
(SELECT item_id, AVG(price) price FROM order_line
GROUP BY item_id) b
where a.item_id = b.item_id
and a.price > b.price

Thank you! It worked.
