6:53 From IGCSE paper 6 I remember when straight lines passes through origin is Directly proportional. When straight line without passing though origin Is proportional. That's the only explanation i could provide on why marking scheme wrote proportional not directly proportional in 8:21 . please correct me if im wrong
