The numbering of the quadrants proceeds counter-clockwise from quadrant I such that quadrant II is the top left quadrant, quadrant III is the bottom left quadrant, and quadrant IV is the bottom right quadrant. Quadrant I is the quadrant in the top right. The axes also divide the coordinate plane into four regions called quadrants as shown in the coordinate plane above. Similarly, the second number represents the position of the point on the y-axis and is accordingly named the y-coordinate. It represents the position of the point on the x-axis. The first number in the pair is referred to as the x-coordinate. The location of a point is given as an ordered pair of numbers, (x 1, y 1). The grid on the coordinate plane above is shown with light gray line segments. A grid is a set of uniformly spaced horizontal and vertical lines. The two axes (plural for axis) intersect vertically at a point called the origin of the coordinate plane.Ī grid is often drawn on a coordinate plane to make it easier to locate a point. x-axis, y-axis, and originĪ coordinate plane is formed by the intersection of a horizontal number line called the x-axis and a vertical number line called the y-axis. Several properties characterize a coordinate plane. The coordinate plane can also be referred to as the Cartesian coordinate plane, as it is used as part of the Cartesian coordinate system. The figure below shows five points in a coordinate plane: A, B, C, D, and E. The coordinate plane can be used to locate points on a plane. The point at which the x and y-axis intersect is known as the origin. Home / geometry / coordinate plane Coordinate planeĪ coordinate plane is a two-dimensional plane formed by the intersection of the x-axis and the y-axis.
