put this solution on YOUR website!I think my solution must have been posted at exactly the same time that you re-posted this problem. I think I corrected that error for you. By the way, I also emphasized that the parentheses notation (-5,2) is NOT appropriate for this type of an answer. There are different notations that (-5,2) could refer to, but THIS is NOT one of them.
