Question 1169716
.


This post is a  NONSENSE.



It will take long time to explain why it is so,  but it is nonsense in every second word.



It is enough to say that the point  L  is not defined in the post;


therefore,  the parts  (c)  and  (d)  are nonsensical.

Let me tell you that creating/composing  Math problems  REQUIRES  certain mathematical qualification,


which is difficult to detect in your post.
