You will have to dig out a 12" wide and 6" deep trench along the perimeter of the slab and fill it with one inch gravel. The grade pitch will continue to erode the dirt under the slab and eventually cause the slab to crack. Replace the dirt and pack it in before you install any gravel.

You should have dug a footing around the slab to begin with. But now, you could put some landscape rock around it, or pour a concrete apron around it.
