The coordinates are often denoted by the letters x, y, and z. The axes may then be referred to as the x-axis, y-axis, and z-axis, respectively. Then the coordinate planes can be referred to as the xy-plane, yz-plane, and xz-plane.
A 2D coordinate plane is formed by the intersection of a horizontal number line called the x-axis and a vertical number line called the y-axis. The two axes (plural for axis) intersect at a point called the origin.
Cartesian Coordinates. In the cartesian system, the x-coordinate of a point is its perpendicular distance from the y-axis. It is measured along the x-axis which is positive along the positive direction and negative along the negative direction. For point P, it is +5 on the positive x-axis.
The xyz coordinate axis system, denoted 3, is represented by three real number lines meeting at a common point, called the origin. The three number lines are called the x-axis, the y-axis, and the z-axis. Together, the three axes are called the coordinate axes.
The X Axis runs horizontally through zero. The Y Axis runs vertically through zero. Axis: The reference line from which distances are measured. The plural of Axis is Axes, and is pronounced ax-eez. Example: Point (6,4) is. 6 units across (in the x direction), and. 4 units up (in the y direction) So (6,4) means:
A typical Cartesian coordinate system is defined by x and y axes. Each axis has a unit of length or distance (such as metres or miles). Any point within the coordinate system is described by a distance relative to both the x and y axes, (x,y).
Illustrated definition of X Axis: The line on a graph that runs horizontally (left-right) through zero. It is used as a reference line so you...
