What is "abscissa" and "ordinate"?

Hi @justsomeone, I appreciate your reply.
If you don’t mind, I’d appreciate if you could tell me the following:

  • Why did you think that each word corresponds to each word?
  • Do you think they are exactly the same( and if possible, why)?

Don’t worry about this question any more, if you have some reason in your mind. Just in case, don’t worry about the possibility that I believe something only by your reply.

I don’t know how to say this but, what you gave has doesn’t work for me without such thing. This time I aim to solve this question for a bigger question, so I try to understand stricter about it. Before getting your reply, I already found words like what you gave me and I explored there to some extent. In such a situation, I’ve been keeping research. In other words, I’m not just keeping waiting for an answer, so I think giving me time is one of your options, even if you try to help me.

I’m sorry if I’m saying too directly or impolitely.
