Natalie said: It is much steeper than it looks. There is no way to actually walk down it.
If it were me, I think I'd work on arresting some of the slide that's bound to occur here first. Since it's too steep to walk it, I'd start by tossing tree trimmings and flat-edged logs over the fence; preferably when there's wet snow there or in other soggy conditions. If even part of some of the logs get wedged into the wet soil they're most apt to stay put long enough to hold the soil and your seeds. Maybe try for some sort of loose herringbone pattern, beginning on the up-slope side of those partially submerged rocks and working your way across the slope toward the deck.
Some of these at least are native wildlife restoration plants, and might be good beginning choices for this difficult area: Thermopsis montana, Castilleja linariifolia, Arctostaphylos uva-ursi, Linum lewisii, Sphaeralcea coccinea, Hedysarum boreale, Cleome serrulata, Achillea millefolium...(more here

I think I'd also toss out any sunflower seeds I happened to get hold of; they're easy to grow, and the large spent stalks will help to provide much needed organic matter for the following year's crop of seedlings.
