What is the meaning of XY coordinates?
x, y coordinates are respectively the horizontal and vertical addresses of any pixel or addressable point on a computer display screen. x and y coordinates can also be specified as values relative to any starting point on the screen or any subset of the screen such as an image.
What is the other name for Y coordinate?
the ordinate
Another name for the y-coordinate is the ordinate. Note: The x-coordinate or abscissa represents the directed distance of the point from the y-axis.
Which best describes the y coordinate of a point?
The vertical value in a pair of coordinates. How far up or down the point is. The Y Coordinate is always written second in an ordered pair of coordinates (x,y) such as (12,5). In this example, the value “5” is the Y Coordinate.
Do you write the X or y coordinate first?
The first number refers to the -coordinate. The second number refers to the -coordinate. Coordinates are written alphabetically – so x comes before y (x, y). One way to remember is ‘you go along the hallway before you go up the stairs’.
Which way does the X and Y coordinates go?
Here is what you’ll need to know: The x-axis goes left and right, the second coordinate is on the y-axis. The y-axis goes up and down. Positive numbers go up or right (depending on the axis). Negative numbers go left or down.
What is the y coordinate for any point on the x axis?
Ordinate or the more familiarly known y-coordinate of a point is defined as the distance from x-axis. i.e., it measures how much distance you go above or below the x-axis. If a point on the x-axis itself, its distance from x-axis is 0. Therefore the ordinate (or y-coordinate) of any point on the x-axis is 0.
What are the X and y axis used for?
The Y axis refers to vertical position (perpendicular to the base) and the X axis refers to the horizontal position (parallel to the base). As seen in Figure 6a below. When aligning vertical rotating machinery, the Z axis is also the center of rotation, however X and Y are used to reference the two axial planes 90 degrees from each other as in
