For this problem you are fixing two out of the nine which means you are left to re-order the rest how you please.
If there is no other constraints for this problem then think about how possibilities you get for each position.
The first position has 7 choices. You fix one of these choices and the second position has 6 (since you already used up 1 for the first). Then you have 5,4,3,2 and 1 choice(s) for the rest of them. These are all independent choices (once you choose the first choice, the second choice only depends on the number of people that are left) so you can multiply these choices.
What does this process give you as an answer?
