TRANSCRIPT
In coordinate Geometry, grid paper is used to locate points. The plane of the grid is called the coordinate plane.
The two axes separate the plane into four regions called quadrants.
Points can lie in one of the four quadrants or on an axis.
X axis
Y axis
The points on the x-axis to the right of the origin correspond to positive numbers.
Origin
To the left of the origin, the points correspond to negative numbers.
Origin
The points on the y-axis above the origin correspond to positive numbers.
Origin
Below the origin, the points correspond to negative numbers.
Origin
An ordered pair of real numbers, called the coordinates of a point, locates a point in the coordinate plane. Each ordered pair corresponds to exactly one point in the coordinate plane.
The point in the coordinate plane is called the graph of the ordered pair. Locating a point on the coordinate plane is called graphing the ordered pair.
