These are essentially arbitrary labels, but there is still some reason why those letters were chosen rather than some other letters such as a and b. Other letters are associated with a larger number of words which might turn out to be applicable to various graphs. A for altitude, b for babies, etc. X is the least used letter of the English (or French - Rene Descartes, inventer of the Cartesian coordinate system, was French)alphabet and therefore it seemed to be a good candidate for a new job, to stand for the unknown in an algebraic equation, and since y is the letter that comes after x, it seemed to have some logical connection, if you wanted to graph two variable quantities against each other.
They are the x and y axes
The x and y axes on the Cartesian plane intersect at the origin at right angles
The ordinate is the y coordinate of a point and the abscissa is the x coordinate of a point and both axes intercept each other at the point of origin (0, 0) on the Cartesian plane.
The axes that divide a plane into regions are called coordinate axes. In a typical Cartesian coordinate system, these are the horizontal x-axis and the vertical y-axis. Together, they create four distinct quadrants in the plane, each representing different combinations of positive and negative values for the x and y coordinates.
The horizontal line is the x axis and the vertical line is the y axis.
They are the x and y axes
The x and y axes cross the origin on the Cartesian plane
The x and y axes on the Cartesian plane intersect at the origin at right angles
The x and y axes on the Cartesian plane intersect at the origin at right angles
The x and y axes intersect at the point of origin at (0, 0) on the Cartesian plane
It is the x axis and the y axis and both axes are found on the Cartesian plane
The ordinate is the y coordinate of a point and the abscissa is the x coordinate of a point and both axes intercept each other at the point of origin (0, 0) on the Cartesian plane.
The horizontal line is the x axis and the vertical line is the y axis.
The coordinate axes are the x and y axes that intersect each other at right angles at the point of origin (0, 0) on the Cartesian plane.
A Cartesian plane is a 2-dimensional, flat surface. The plane has two mutually axes that meet, at right angles, at a point which is called the origin. Conventionally the axes are horizontal (x-axis) and vertical (y-axis) and distances from the origin are marked along these axes. The position of any point in the plane can be uniquely identified by an ordered pair, (p, q) where p is the distance of the point along the x-axis (the abscissa) and q is the distance of the point along the y-axis (the ordinate).
They are found on the Cartesian plane by means of the x and y axes
The horizontal line in the Cartesian plane is called the x-axis or x-coordinate.
