I call this 6 outs, with the check raise, someone obviously has hit their set or two pair. Your 9 most likely wont help, the straight is what youre looking for, the back door flush draw is likely to not be good either, but may be... so add 1 out...

For 7 outs, you are just at the right odds to call, but I'd probably fold because the pot really isnt large enough...
