If the abscissa is positive, the point belongs to either the first or fourth quadrant. If the ordinate is zero, the point lies on the X-axis.
If the abscissa is zero, the point lies on Y-axis
The ordinate gives the vertical distance of a point.įor a set of points with the same abscissa and different ordinates, the line joining the points is a straight line parallel to Y-axis and perpendicular to X-axis.įor a set of points with the same ordinate and different abscissa, the line joining the points is a straight line parallel to X-axis and perpendicular to Y-axis. The abscissa gives the horizontal distance of a point. The ordinate of a point is the perpendicular distance of the point from the X-axis. The abscissa of a point is the perpendicular distance of the point from the Y-axis. The term ordinate corresponds to the value of the y coordinate of a point. The term abscissa corresponds to the value represented by the x coordinate of a point. Also, state the quadrant to which the point belongs. Identify the ordinate and abscissa of the points represented by A, B, C, D, and E in the coordinate system example given in the figure. The Ordinate in Coordinate System Examples It is in the fourth quadrant if x is positive and y is negative.Īn example of plotting a point P (2, 3) is shown in the figure below. The point is in the third quadrant if both x and y are negative. It lies in the second quadrant if x is negative and y is positive. The point lies in the first quadrant if both x and y are positive. If a point is represented by A (x, y), it is plotted on a cartesian plane at a distance of x unit from the Y-axis and a distance of x units from the Y-axis. the vertical distance of a point from the origin. The ordinate in the coordinate system of a point gives the perpendicular distance of a point from the X-axis. The perpendicular axes divide the plane into four equal parts called the quadrants. In other words, the cartesian plane is a representation of two number lines mutually perpendicular to each other. The cartesian plane consists of two axes X and Y mutually perpendicular to each other. Similarly, a point in a cartesian space is represented as P (x, y, z). The point in a cartesian plane is represented along with its coordinates as P (x, y). The three dimensions of the object represented by X, Y, and Z axes are length, width, and height respectively. Similarly in the cartesian space, the object is represented as a 3-dimensional view. The two dimensions: length and width are represented by the X and Y coordinates respectively. The cartesian plane is a two-dimensional representation of geometric figures. It is used to represent the position of an object along with its dimensions in a plane or space. The Cartesian coordinate system was developed by Rene Descartes, a great Mathematician. For a set of points having the same ordinate and different abscissa, the line joining these points is a straight line parallel to the X-axis. The ordinate gives the horizontal distance of a point from the origin. It refers to the perpendicular distance of the point from the X-axis and is parallel to the Y-axis. The ordinate in the coordinate system refers to the y coordinate of any point in a cartesian plane. Ordinate is a term associated with the planar representation of a point in the cartesian coordinate system.
