![]() The point in which the two axes meet is called the point of origin. In the two-dimensional version of the system, the lines are commonly designated as the x-axis (usually the horizontal one) and the y-axis (the vertical one). It can be used to represent two- or three-dimensional space and, depending on that, it consists of two or three mutually perpendicular lines called axes (the singular form is axis). It was invented in the 17 th century by the French philosopher and mathematician René Descartes and it started a revolution in mathematics, as it was the first systematic link between Euclidean geometry and algebra. The Cartesian coordinate system is the most well known coordinate system. If it is a positive number, it lays on the right side of the point of origin. ![]() If the coordinate is a negative number, it is found on the left side of the point of origin. The coordinate in this system shows the distance of the point in question from the point of origin. It is basically a line divided in number of equal parts with a randomly chosen point of origin (O). The number line is probably the first coordinate system you will come across during your education. Since the others require some more advanced mathematics that was not covered on this site yet, we are going to turn our attention two the two most commonly used systems – the number line and the Cartesian system. There are several coordinate systems that are widely in use: the number line, the Cartesian coordinate system, the polar coordinate system, cylindrical and spherical coordinate systems. In other words, it tells you which number refers to which axis. The order of the coordinates is important and it indicates the axis of reference for that specific coordinate. Coordinates are a set of numbers (one, two or more of them) that determine the position of a point or a geometric body within a coordinate system.
