Coordinate Plane Graph
Concept
A coordinate plane is a two-dimensional surface formed by two number lines. It is formed when a horizontal line called the X-axis and a vertical line called the Y-axis intersect at a point called the origin. The numbers on a coordinate grid are used to locate points. A coordinate plane can be used to graph points, lines, and much more. It acts as a map and yields precise directions from one point to another.
Rules
1. Start at (0,0), which is the point where the axes meet (origin).
2. Move (x) units to the right or left on the x-axis.
3. Move (y) units up or down on the y-axis.
4. Graph the point.
Example
Graph the point (2,3).
Solution
1. Start at (0,0), which is the point where the axes meets the (origin).
2. Move 2 units to the right on the x-axis.
3. Move up 3 units on the y-axis.
4. Graph the point (2,3).

Coordinate Plane – It is a two-dimensional plane formed by the intersection of a vertical line called the y-axis and a horizontal line called the x-axis. These are perpendicular lines that intersect each other at zero, and this point is called the origin.
Coordinates are a set of two values that locate a specific point on a coordinate plane grid, better known as a coordinate plane. A point in a coordinate plane is named by its ordered pair (x, y), written in parentheses, corresponding to the X-coordinate and the Y-coordinate. These coordinates can be positive, zero, or negative, depending on the location of the point in the respective quadrants.
Ordered Pair – An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), having two values written in a fixed order within parentheses. It helps to locate a point on the Cartesian plane for better visual comprehension.
x-coordinate – tells the horizontal position.
y-coordinate – tells the vertical position.
