Koordinátapárok

Koordinátapárok are pairs of numbers used to define a position in a two-dimensional space. They are typically written as (x, y), where the first number, x, represents the horizontal position and the second number, y, represents the vertical position. The x-axis is the horizontal line, and the y-axis is the vertical line. The point where the x-axis and y-axis intersect is called the origin, and its coordinates are (0, 0).

In a Cartesian coordinate system, a koordinátapár uniquely identifies every point on a plane. For example, the koordinátapár (3, 2) indicates a point that is 3 units to the right of the origin along the x-axis and 2 units up from the origin along the y-axis. Negative values for x indicate positions to the left of the origin, and negative values for y indicate positions below the origin.

Koordinátapárok are fundamental in various fields, including mathematics, physics, computer graphics, and geography. They are used to plot graphs, describe the location of objects, and perform geometric transformations. The concept of coordinates extends to three-dimensional space, where points are represented by koordinátapárok of three numbers (x, y, z).
