Coordinate Plane

The coordinate plane, also known as the Cartesian plane, is a two-dimensional system used to locate points. It consists of two perpendicular number lines, the x-axis, and the y-axis, which intersect at their zero points, called the origin.

Parts of the Coordinate Plane:

Origin: The point where the x-axis and the y-axis intersect, denoted by (0, 0).
X-Axis: The horizontal number line.
Y-Axis: The vertical number line.
Quadrants: The four sections of the coordinate plane formed by the intersection of the x-axis and the y-axis. They are labeled as Quadrant I, Quadrant II, Quadrant III, and Quadrant IV, in a counterclockwise direction.

Coordinates:

Points on the coordinate plane are located using ordered pairs (x, y), where x represents the horizontal position along the x-axis, and y represents the vertical position along the y-axis.

Plotting Points:

To plot a point, locate the x-coordinate on the x-axis, then move vertically to the y-coordinate on the y-axis, and mark the point at their intersection.
