hi Dawn0388
Welcome to the forum.
The x-y system of coordinates was invented by the mathematician Descartes.

But you don't have to use x and y at all. For example to draw a graph of velocity changes with time, you might have 't' across and 'v' up.
You'll find more about coordinates at

Y = [+]

[-]
But what are X and Y stand for? Are these just a alphabet?
