This problem has been in web2.0calc, but the problem is slightly different.

You have to go 4 up and 5 across (in any order)

So I think it will just be    9!/(5!4! )= 126

A question for you. If it was a 7 by 9 grid what would the answer be?

Good to see that you are having a go but it is not correct.

 

Look at my first answer and try again.
