The first and second coordinates are called the abscissa and the ordinate of P, respectively; and the point where the axes meet is called the origin of the coordinate system. The coordinates are usually written as two numbers in parentheses, in that order, separated by a comma, as in (3, −10.5).

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. This x-coordinate is called the abscissa. In the cartesian system, the y-coordinat...
The cartesian coordinate system for a one-dimensional space is a straight line having the origin O and a positive side and a negative side of the line. One-dimensional means either the plane have a horizontal line or a vertical line. If the line is horizontally plotted then the right side is taken as positive and the left side is taken as negative....
A cartesian plane divides the plane space into two dimensions and is useful to easily locate the points. It is also referred to as the coordinate plane. The two axes of the coordinate plane are the horizontal x-axis and the vertical y-axis. These coordinate axes divide the plane into four quadrants, and the point of intersection of these axes is th...
The three-dimensional cartesian coordinate system consists of three axes, the x-axis, the y-axis, and the z-axis, which are mutually perpendicular to each other and have the same units of length across all three axes. Similar to the two-dimensional coordinate system, where the point of intersection of these three axes is the origin O, and these axe...
The distance between two points (x1,y1)(x1,y1) and x2,y2)x2,y2)is equal to the square root of the sum of the squares of the difference of the x coordinates and the y-coordinates of the two given points. The formula for the distance between two points is as follows. D = √(x2−x1)2+(y2−y1)2(x2−x1)2+(y2−y1)2
The slope of a line is the inclination of the line. The slope can be calculated from the angle made by the line with the positive x-axis, or by taking any two points on the line. The slope of a line inclined at an angle θ with the positive x-axis is m = Tanθ. The slope of a line joining the two points (x1,y1)(x1,y1) and x2,y2)x2,y2) is equal to m =...
The formula to find the midpoint of the line joining the points (x1,y1)(x1,y1) and x2,y2)x2,y2)is a new point, whose abscissa is the average of the x values of the two given points, and the ordinate is the average of the y values of the two given points. The midpoint lies on the line joining the two points and is located exactly between the two poi...
The section formula is useful to find the coordinates of a point that divides the line segment joining the points (x1,y1)(x1,y1) and (x2,y2)(x2,y2) in the ratio m:nm:n. The point dividing the given two points lies on the line joining the two points and is available either between the two points or on the line, beyond the two points. (x,y)=(mx2+nx1m...
This equation of a line represents all the points on the line, with the help of a simple linear equation. The standard form of the equation of a line is ax + by + c= 0. There are different methods to find the equation of a line. Another important form of the equation of a line is the slope-intercept form of the equation of a line (y = mx + c). Here...
The equation of a plane in a cartesian coordinate system can be computed through different methods based on the available inputs values about the plane. The following are the four different expressions for the equation of plane. 1. Normal Form: Equation of a plane at a perpendicular distance d from the origin and having a unit normal vector ^nn^ is...
In a Cartesian coordinate system, the origin is the point where the axes of the system intersect. [1] The origin divides each of these axes into two halves, a positive and a negative semiaxis. [2]
Cartesian coordinates, system of describing the position of points in space using perpendicular axis lines that meet at a point called the origin. Any given point’s position can be described based on its distance from the origin along each axis.

Aug 30, 2024 · On the horizontal axis, the positive direction is to the right, negative is to the left. On the vertical axis, the positive direction is up, negative is down. The point (0, 0) is called the origin of the coordinate system, and is the starting point for all point plotting.
The point (0,0) is given the special name "The Origin", and is sometimes given the letter "O". Abscissa and Ordinate. You may hear the words "Abscissa" and "Ordinate" ... they are just the x and y values: Abscissa: the horizontal ("x") value in a pair of coordinates: how far along the point is.
Any point in the plane can be reached from the origin by travelling a certain distance \(x\) along the horizontal axis and a certain distance \(y\) along the vertical axis. The numbers \((x,y)\) are the coordinates of the point. The origin itself has coordinates \((0,0)\).
