So i'm doing some joint pdf/pmf stuff in stats but having a hard time just figuring out how to sketch the graphs.

I've got 0<x<y and x+y<2

Gotta figure out how to do this or else setting up integral bounds will be much more difficult

I need to know how to go about doing these graphs. I know what this particular graph looks like already

For x+y<2 I've just graphed x+y=2.

Somehow there's another line coming up --- y=x

Logically it makes sense that there would be a line there because it satisfies 0<x<y but I just thought there was an easier way to do these.

Should be the area between those two lines:
