- Definition of Y-Axis. The Coordinate plane is formed by the intersection of two number lines, a horizontal number line and a vertical number line. The vertical number line is called the y-axis. Examples of Y Axis. The figure shows the coordinate plane formed by the intersection of the x and y-axes.

Coordinate Graphing A coordinate grid has two perpendicular lines, or axes, labeled like number lines. The horizontal axis is called the x-axis. The vertical axis is called the y-axis. The point where the x-axis and y-axis intersect is called the origin. The numbers on a coordinate grid are used to locate points. Each point can be identified by an ordered pair of numbers; that is, a number on the x-axis called an x-coordinate, and a number on the y-axis called a y-coordinate. Ordered pairs are written in parentheses (x-coordinate, y-coordinate).

What does the axis mean in prescription for glasses? This describes the lens meridian that contains no cylinder power to correct astigmatism. The axis is defined with a number from 1 to 180. The number 90 corresponds to the vertical meridian of the eye, and the number 180 corresponds to the horizontal meridian.

What is the x axis: definitions of the main terms required for understanding the coordinate systems The x axis is a horizontal line and the y axis, which is perpendicular to the x axis, is a vertical line. The rectangular coordinate system that can be sued for determination of the concrete position of some geometric figure in the three-dimensional space requires selecting three mutually perpendicular lines: x axis, y axis and z axis.

What is an X-Y Axis? An x-y axis, also known as a cartesian coordinate system or a coordinate plane, is a two-dimensional plane of points defined uniquely by a pair of coordinates. What does that mean? Every point on the plane is represented by two numbers, known as its coordinates.

- The Axis is the last number in a formula for astigmatism. This is a number anywhere between 0 and 180, and is measured in degrees. The axis denotes the position of the astigmatism as far as where it is taking place in the curve of the eye.

Relation between increase in length of hip axis in older women between 1950s and 1990s and increase in age specific rates of hip fracture The line of the hip axis was defined as passing through the mid-point of the femoral neck and the point on the femoral head (identified with a compass) furthest from the neck's mid-point. This definition gave an objective and reproducible method for defining the axis.

Axis Definition Of Axis. An Axis is a line about which a figure is drawn, measured, rotated, etc. The horizontal line and the vertical line on a coordinate plane are known as the X-axis and the Y-axis respectively. The plural of axis is axes. In a three-dimensional coordinate plane X, Y, and Z are the three axes.

What is the x axis: definitions of the main terms required for understanding the coordinate systems The horizontal line is usually called the x axis, whereas the vertical line is called the y axis. The point that determines the location in which these two lines intersect each other is called the origin. The number, which is associated with the sought-for point, is usually called the coordinate of the point.
