The position of any point in the plane can be represented by an ordered pair of numbers (x, y). Signing up with Facebook allows you to connect with friends and classmates already Franchisee | If we take two number lines, one horizontal and one vertical, and then combine them in such a way that they intersect each other at their zeroes, and then they form a Cartesian Plane. It is mentioned here that in many circumstances the position of a point needs to be described with reference to more than just one line. The y - coordinate of a point is marked by drawing a perpendicular from the x-axis measured a length of the y-axis .It is also called the Ordinate. If x ≠ y, then (x, y) ≠ (y, x), and (x, y) = (y, x), if x = y. Then from that point go upward and count to 4. The point where these two lines intersects each other is called the origin. Practical examples are provided to help students understand the matter, like telling the position of a dot on a sheet of paper. Sitemap | Similarly, the left and the downward directions are the negative directions as all the negative numbers lie there. Likewise, we can plot all the other points, like (-3, 1) and (-1.5,-2.5) in the right site figure. Mark that point as the coordinate (6, 4). The horizontal line is known as the x-axis and the vertical line is known as the y-axis. In the above figure, OB = CA = x coordinate (Abscissa), and CO = AB = y coordinate (Ordinate). One of our academic counsellors will contact you within 1 working day. The coordinates of the origin are (0, 0). Get Revision notes of Class 9th Mathematics Chapter 3 Coordinate geometry to score good marks in your Exams. We write the coordinates in brackets. Coordinate geometry has traditionally been attributed to RenÃ© Descartes (1599â1650) and Pierre de Fermat (1601â1665) who independently provided the beginning of the subject as we know it today. The Cartesian plane is dividing into four quadrants named as Quadrant I, II, III, and IV anticlockwise from OX. The point with coordinates (4, 2) has been plotted on the Cartesian plane shown.
