Origin. The numbers represent where you are on your graph. The first number (0) is your X, which is horizontal. The second number (0) is your Y, and that is vertical. For example, (4,-2) is 4 spaces the the right vertically and -2 is down 2 spaces vertically. For yours, because it is (0,0) you don’t move. That means that you start at that point; it’s your origin.
