Quadrant one: positive x and positive y. (5,6)
Quadrant two: negative x and positive y. (-5,6)
Quadrant three: negative x and negative y. (-5,-6)
Quadrant four: positive x and negative y. (5,-6)
the y-axis goes up and down so im guessing the x coordinates will be 0 and the y will be whatever you want it to be. the same goes for the x-axis excepted switched around.
Apologies if I got any of these wrong, and please comment if you are confused so I can explain more.
