Graphing Points on the Coordinate Plane
Two number lines that intersect at right angles form a coordinate plane.
The horizontal axis is the x-axis and the vertical axis is the y-axis. The axes intersect at the origin and divide the coordinate plane into four sections called quadrants.
An ordered pair of numbers identifies the location of a point. These numbers are the coordinates of the point on the graph. Point B has coordinates (−2, 4).
The x-coordinate tells you how far to move right (positive) or left (negative) from the origin. The y-coordinate tells you how far to move up (positive) or down (negative) from the origin. The origin is the point (0,0).
Identifying Coordinates
Name the coordinates of point Z in the graph.
The coordinates of Z are (−2, −3).
Graphing Points
Graph the point A(3, −4) on the coordinate plane.
Coordinate Plane Quadrants
There are four quadrants in a coordinate plane.
If you are still having trouble, view this youtube video...
Now try this for extra practice...
Graph these coordinates. Name which coordinate these points are in.
1) (2,3) 1) (-5, -6)
2) (-4,-5) 2) (3 , 8)
3) (3, -4) 3) (-4 , 1)
4) (-6, 8) 4) (2, -9)
5) (0,0) 5) (0 , 0 )
