Talk:Y-intercept

Untitled

Why Y why not Q?

Historical reasons. Back when "modern" algebraic symbolism was introduced in the 16th Century or so, "x" was chosen to represent the unknown variable. So "y", being the next letter, is naturally your second variable. Specifically in the case of "y-intercept", it's probably Descartes' fault. --Bth 15:37, 10 March 2006 (UTC)[reply]

Root (mathematics)

Mentioning Root (mathematics) would be a great addition to the article. --Abdull 15:27, 31 May 2006 (UTC)[reply]

Formula

The formula for Y-Intercept would be a nice add-on —The preceding unsigned comment was added by Ianboy13 (talk • contribs) 01:42, 12 April 2007 (UTC).[reply]

Fixed redlink in article

In the last paragraph, the text I/V-characteristic linked to... nothing! So I fixed it, linked it to Current-voltage characteristic, and added an explanation of the use of I as a variable. Please discuss before making any reverts relating to this edit!

Thanks,

sounds more complex than it needs to be

This article reads like someone wanted to try to impress everyone. I remember seeing descriptions/definitions in textbooks less puffed up than this article. Did a lawyer write this? — Preceding unsigned comment added by 72.47.30.187 (talk) 13:54, 21 August 2013 (UTC)[reply]

Expansion of this article with citations, examples and images

Hiya. Firstly, I want to thank the editors for all of the useful information contained in this article. I am not very good at remembering all the bits and pieces so when I went to translate it, this was great. When working on the translation, I research citations and added examples and created images. The result in English is at User:Lfahlberg/sb_y-intercept. (BTW: Rows of 4 images look good on a tablet or ipad and on a regular computer monitor, but 4 did not cover the examples I thought important, so I made 8. I am a visual learner and images are easy to understand (and easy to translate) and so am big on images.) Please tell me what you think about this proposal. Also, I was unsure about the See also list and the Categories (I would love categories Basic Functions, Basic Algebra, but they do not exist). Thank-you for reading.

Ordinate Intercept

Can the y-intercept also be called the ordinate intercept.

The ordinate is the vertical axis and the y-intercept is the vertical intercept. So, I believe the term ordinate intercept will also make sense.

The ordinate is the second coordinate of a coordinate pair in the Cartesian system. It is not the name of the vertical axis (or y-axis). So this would not really make any sense. Also, even if it did work, Wikipedia would not be the place to bring it up as there would be no reference for it. --Bill Cherowitzo (talk) 03:23, 9 July 2018 (UTC)[reply]

It is commonly used. [1] wumbolo ^^^ 21:36, 20 January 2019 (UTC)[reply]

Interesting. All the references were from science journals and I didn't see any from math articles. My own perspective is from mathematics and I was unaware of these, what I would call, misuses of terminology. References could probably be found, but not in the mathematics literature. --Bill Cherowitzo (talk) 22:23, 20 January 2019 (UTC)[reply]
