Say I have a list of some conditions, such as

list = {y<x,x<0}

And I'd like to plug this into RegionPlot, such as

RegionPlot[y<x && x<0, {x,-1,1}, {y,-1,1}]

but I can't figure out how to do so. I'm not sure why And[list] doesn't produce the desired result, this seems like this should be the default behavior for And, unless there's a way to do this that I'm not aware of.

Try And @@ {y < x, x < 0} (and look up Apply). – Henrik Schumacher Feb 13 '19 at 20:44
Oh thanks so much, that makes perfect sense now, I had wondered what @@ did. – Kai Feb 13 '19 at 20:45
