Step-by-step explanation:
Coordinates of Points
A point is the basic relationship displayed on a graph. Each point is defined by a pair of numbers containing two coordinates.
A coordinate is one of a set of numbers used to identify the location of a point on a graph.
Identifying the x-coordinate
The x-coordinate of a point is the value that tells you how far from the origin the point is on the horizontal, or x-axis. To find the x-coordinate of a point on a graph:
- Draw a straight line from the point directly to the x-axis.
- The number where the line hits the x-axis is the value of the x-coordinate.
Identifying the y-coordinate
Now that you know how to find the x-coordinate of a point, you have to be able to find the y-coordinate.
The y-coordinate of a point is the value that tells you how far from the origin the point is on the vertical, or y-axis. To find the y-coordinate of a point on a graph:
- Draw a straight line from the point directly to the y-axis.
- The number where the line hits the axis is the value of the y-coordinate.
Notation for Identifying Points
Once you have the coordinates of a point you can use the ordered pair notation for labeling points. The notation is simple. Points are identified by stating their coordinates in the form of (x, y). Note that the x-coordinate always comes first.
