i can graph x=1, but how to graph x>1?

Just "back up" (delete) over the = sign and you will get a pop up menu with the inequalities

love it but after I enter two functions such as 

Y>1

Y<2x+1

How do I delete just one or the other or both without selecting delete all? del and clear do not seem to work here.

Thanks.

del should work.  Just click on the line part of the one you want to delete (at which point it should be flashing), and then press del.

I think you hover over the graph itself to delete, I will go get my handheld to check

I agree with Marc that clicking on the graph itself to delete is easiest, you can also point to the graph, right click (ctrl menu) and choose delete.  This way also reminds you about all the other good stuff you can do with right click.

You can't plot a vertical line on the graphs page.

Your best options are build a line by two points and display its
equation or so the ugly trick of drawing a line y>mx+b, where m is
very, very big and b is the value you're interested in, in this case
1.

i can draw vertical line: using parametric: x1=3, y1=t.(for the line
x=3)

i like your suggestion! it is a very clever way to overcome the
limitation of the deice.thanks!
