I can control the slope of concrete when the edges are two walls?

One thing I've done in similar situation is to form up each end a brick
(plus joint) width or length away from wall and then pour. After set,
backfill edges and lay brick or pavers along edges.

Another way is to simply pour the center section then use it and
freehand the narrow outer section w/ a formed edged between the sections.

OTOH, if you use foam board or similar behind form against wall there's
enough give to get a form out if you leave a portion to get ahold of for
starters and don't fit it too tightly at ends so it's got some wriggle room.

Then again, I've seen the forms left in place and when the finally
disintegrate, fill it in. Not my preferred choice, but in TN one saw
lots of stuff...
