Y coordinate problem

hello everyone.
I am pretty new to qbasic. I am writing a simple program to graph up to a polynomial and I've got it working except for one thing. My Y coordinate is upside down. I know this is because qbasic reverses the Y coordinate. I there a way to change it so that the Y increases as you move from the bottom to the top of the screen? (like a normal Cartesian plane). Thanks for putting up with a newbie question.

NO, but your brain can adapt the code for it. Try negative increments.

Thanks! The negative increments worked perfectly. I feel stupid now for not realizing something that obvious, but oh well.
