Briefly describe how you would graph in your Algebra class (the x-y coordinate plane?

So the x=y line on a graph

Well there are 4 different quadrants one positive and one negative and two mixed with each, it they are both positive go right and up, if x is positive and y negative then go to the right and down, but if x is negative and y is positive go left and up, but if both are negative go left and down
