Implement IIR filter

Hello

 

I am trying to implement an IIR filter, but cannot seem to find any good information on the internet.  All I can find are FIR guides.  My transfer function is b=[1 -1] and a=[1 -.9].  How can I implement this in system generator?  Is there some kind of block I can use for IIR, or do I have to create something like this?

 

Any help would be greatly appreciated, as I am new to this and have no clue how to proceed.
