Plumbing for new kitchen sink

I'm installing a new sink in my kitchen. It has a large 9" deep bin and a small vegetable bin 7" deep. I'm going to install the garbage disposal to the vegetable sink.

All of the pipes connect and flow out directly behind the larger sink. When I run the piping from the disposal to the main drain pipe, should I have a slight pitch downward or can it be level? I'm afraid junk from the disposal might back up if the pipe is level. What is considered the normal installation in this situation?

Thats why you should leave the water running 4 or 5 seconds after you shut the disposal off.
The pipe after the trap could be verticle. if it doesn't have something pushing it out of the trap, it makes no difference.
