What is this, simple wiki?
Why is this page so entrenched in the language of "x and y axes" and "horizontal and vertical axes"? The entire point of referring to these axes as "abscissa and ordinate" is for free yourself from a specific reference. Yes, it is usual -- in cartesian coordinates -- that the abscissa is x and the ordinate is y, but that's not *always* the case (consider for example action occurring in the y-z plane or the z-x plane).

Incorrect Redirect
You know, the abscissa refers specifically to the value of the x-coordinate, not the entire Cartesian coordinate system. _____________________________________________ Is abscissa the correct term? As it means cut off and away. Would the ray still be called an abscissa? I can understand a line segment being cut off, done, finalized in measure, but would the ray, with a part still continuing to infinite still count or apply? If its a ray and not a segment? Is there another term? — Preceding unsigned comment added by 173.241.110.194 (talk) 03:22, 21 February 2018 (UTC)
Necessarily horizontal?
$0.02 We often think of the abscissa as the horizontal axis but would it not be more correct to think of the abscissa as the axis of the independent variable. Using the ordered pair (x,y), x would be the independent variable and y the dependent variable. The horizontal axis is just a convention and we could as easily rotate the whole thing by some random angle. — Preceding unsigned comment added by Koehn (talk • contribs) 22:26, 10 June 2011 (UTC)
abscissa
Abscissa is denoted as 'X' coordinate. — Preceding unsigned comment added by 118.95.43.40 (talk) 12:50, 6 September 2011 (UTC)
Added a little extra explanation of the abscissa by analogy to an independent variable in a model, and backed it up with a citation. I also gave the image a new caption that actually said something about the abscissa. - Bryanrutherford0 (talk) 23:38, 14 July 2013 (UTC)
Etymology (and origin)
I added one, and positioned it similarly to that that appears in hypotenuse Rt3368 (talk) 00:45, 11 September 2015 (UTC)
Abscissa needs disambiguation
Abscissa is an entomological term for a section of wing vein between two consecutive cross veins, or between the final cross vein and the wing margin.

Is the definition as axes true?
In common usage, the abscissa refers to the horizontal (x) axis and the ordinate refers to the vertical (y) axis of a standard two-dimensional graph.
Is this really true? Are they really the axes in anyone's mind? It is not taught that way in math classes.
The dictionary definition and other web references say that it is either the value of the horizontal coordinate of the point (as stated just below in this article), or the finite perpendicular segment from the point in question to the vertical axis.
If this is really a "common usage", it still has to be documented.
