![]() The point of intersection of these lines is the point (2, 3).Draw a line upwards from the plotted abscissa and a line towards the right from the plotted ordinate.Since both the x-coordinate and y-coordinate are positive, we can conclude that the point lies in Quadrant I.It is 3 units up from the origin as the y-coordinate is positive. Next, we plot the ordinate which is 3.It is two units to the right of the origin as x is positive.First, we identify the abscissa, which is 2, and plot it on the graph.Given below is a detailed explanation on how to plot the points on a cartesian plane. Here 25 is the abscissa and 10 is the ordinate.Ĭonsider the point (2,3 ). In other words, the abscissa is the horizontal distance of the point from the origin and the ordinate is the vertical distance of the point from the origin.įor example, consider a point (25, 10). In a cartesian plane, the x-coordinate of a point is called the abscissa and the y-coordinate of a point is called the ordinate.

The two axes extend infinitely in both directions which are represented in diagrams by arrows on both ends. There are two axes which are the horizontal line called the x-axis and the vertical line called the y-axis. If the point lies below the origin the y coordinate will be negative.Ĭoordinates of A Point in Three DimensionsĮquation of a Plane in Three-Dimensional SpaceĪxes are the two perpendicular lines that form the cartesian plane. If the point lies on the left side of the origin the x- coordinate will be negative. The same principle can be applied to any point marked on the graph. It is 3 away from the origin horizontally and 5 away from the origin vertically. The coordinates of the origin are (0,0).įor example, consider point A marked on the graph.X-coordinate is the horizontal distance from the origin and the y-coordinate is the vertical distance from the origin.A point on the plane is represented as an ordered pair (x,y) with x and y are the two coordinates.The two lines are commonly referred to as the axes and the point they intersect at is the origin.Cartesian Plane in Mathematics is defined as a graph with two perpendicular lines called the x-axis (horizontal) and the y-axis (vertical) that can be used to indicate the position of any point on a plane. ![]()
