The horizontal axis is the x-axis or the abscissa, whereas the vertical axis is the y-axis or ordinate. The two lines, vertical and horizontal that go never-ending in a coordinate plane are known as axes. Have you seen a coordinate plane yet? What does it look like? A coordinate plane consists of axes, origin, and quadrants. Why a rectangular coordinate system? Because the entire plane looks like a rectangle! Before moving further to understanding the coordinate plane, let us see the parts in a coordinate system. Rene Descartes was the first to define a rectangular coordinate system by which we can represent each point with the help of numbers, called coordinates. The two-dimensional coordinate plane is the Cartesian plane, named after a well-known French mathematician, Rene Descartes. They are perpendicular to each other, meaning they will form a 90-degree angle at their meeting point. The horizontal axis is known as the x-axis, and the vertical axis is known as the y-axis. A coordinate plane is a two-dimensional (three-dimensional, while considering 3D objects) plane consisting of vertical and horizontal axes. And these coordinates are represented in a coordinate plane. What is a coordinate plane: Learning geometry in a new wayДЄs mentioned above, coordinates help us locate an object anywhere in the world. Curious to know what coordinates are or what is a coordinate system? Continue reading further to learn more. That way, it is easier to locate the object within no time. Sailors use the coordinate plane concept to track their way back home and draw maps. What is the use of representing the shapes in such a way? In practical life, we need to know the coordinates of any place or position of a person. But, do we know that these objects can be represented on paper by specific knowledge of axes and planes? We draw shapes in a 2D plane, i.e., only in two directions x and y. Even many shapes are two-dimensionally present around us. Note how the signs of each change in each quadrant.We have acknowledged the fact that various objects around us are three-dimensional. The first number after the A is the x-coordinate and the second the y-coordinate. Drag the origin point around, including dragging it all the way into a corner to show only one quadrant.In the figure at the top of the page, first press 'reset'. In the diagram above, you can drag the origin all the way into any corner and display just one quadrant at a time They are also sometimes labelled with Roman numerals: I, II, III and IV. It is conventional to label them with numeralsД«ut we talk about them as 'first, second, third, and fourth quadrant'. In the diagram above they are labelled Quadrant 1,2 etc. The first quadrant, by convention, is the top right, and then they go around counter-clockwise. The two axes divide the plane into four areas called quadrants. In the figure above you can drag the origin point to reposition it to a more suitable location at any time. The origin is the point from which all distances along the x and y axes are measured. The point where the two axes cross (at zero on both scales) is called the origin. They are shown every 5 units in the figure above, but can be any increment, and need not be the same on both axes. These are labels to help judge the scale. The horizontal scale is called the x-axis.ДЄs you go to the right on the scale from zero, the values are positive and get larger.ДЄs you go to the left from zero, they get more and more negative.ДЄs you go up from zero the numbers are increasing in a positive direction.ДЄs you go down from zero they get more and more negative.ДЄlong each axis you will see small tic marks with numbers. These are the horizontal and vertical distances of the point from a specific location called the origin. Points on the plane are located using two numbers - the x and y coordinates. The plural of axis is 'axes' (pronounced 'AXE-ease'). It has two scales, called the x-axis and y-axis, at right angles to each other. The coordinate plane is a two-dimensional surface on which we can plot points, lines and curves.
