Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

Codewars Forums - Kata Best Practices - Make Sure Content is New
This topic on calculating the distance between two points in 2D space (and actually in the general case of N-dimensions as well) has already been covered by multiple approved and/or Beta Kata as demonstrated by @Voile who kindly provided the links to two such Kata as evidence. Therefore, this Kata fails to present novel content to the user undertaking the Kata and thus provides no additional value to CW. The lack of novel content in a Kata as an Issue is recognised as an official CW stance so you may not resolve this Issue prematurely without addressing it. You must unpublish this Kata and rework it such that it is sufficiently unique from all other Kata currently on CW before re-publishing it to adequately address this Issue.
