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. This means that the point is located 5 units to the left of the y-axis and on the x-axis.Ordinate is a term associated with the planar representation of a point in the cartesian coordinate system. The point (-5, 0) has an abscissa of -5 and an ordinate of 0.This means that the point is located 1 unit to the right of the y-axis and 3 units below the x-axis. The point (1, -3) has an abscissa of 1 and an ordinate of -3.This means that the point is located at the origin, which is the intersection of the x-axis and y-axis. The point (0, 0) has an abscissa of 0 and an ordinate of 0.This means that the point is located 2 units to the left of the y-axis and 6 units above the x-axis. The point (-2, 6) has an abscissa of -2 and an ordinate of 6.This means that the point is located 3 units to the right of the y-axis and 4 units above the x-axis. The point (3, 4) has an abscissa of 3 and an ordinate of 4.Ordinate: The y-coordinate of a point on a two-dimensional coordinate system.Y-axis: The vertical line in a coordinate system.X-axis: The horizontal line in a coordinate system.Coordinate system: A system of lines that intersect at a point called the origin and are used to locate points in two dimensions.Abscissa: The x-coordinate of a point on a two-dimensional coordinate system.The abscissa indicates how far the point is from the y-axis, while the ordinate indicates how far the point is from the x-axis. The position of a point on the coordinate system is represented by an ordered pair (x, y), where x is the abscissa and y is the ordinate.Ī point on the coordinate system can be located by moving along the x-axis to the position of the abscissa and then moving along the y-axis to the position of the ordinate. The coordinate system is made up of two perpendicular lines, known as the x-axis and y-axis, which intersect at a point called the origin. An abscissa, also known as the x-coordinate, is a value used to describe the position of a point on a two-dimensional coordinate system.
