Stupid little brother its a brush, if it isn't in there (WHICH IT SHOULD), you should be able to get it from Deviant Art.
I can't find the stupid "scan line" style.
im curious about this does PHOTOSHOP downloaded for free????
geez...you guys are really new to Ps eh? just make the damn pattern yourself.....make a 3x3 pixel new document, transparent and put 3 pixels from one corner to the other then go into Edit->Define Pattern then you can just save it and BAM you got yourself a scanline pattern:
