Should I just call his raise here or is a 3-bet good?

I chicken out here. He is probably sitting on a 9 too and the only hands I beat are now 92,93,94,97 and 98. Sure, it sounds like something he can have but judging from the action on the other streets im not sure.

Final Pot: 17.50 BB.

Line check? My conclusion is that I should have slowed down on the turn right?
