Maya newbie here,

I have a strange red diagonal line in my perspective view port only that will not go away. Not sure what I clicked or task I did so I'm just stumped.

Also as I left mouse click and drag across screen another one appears but will not stay as I release mouse button. Little clue as to what setting I might have accidently turned on by accident.
Please help.

Screen shots attached.
