Study Notes

The coordinate plane is a 2-dimensional surface with an x-axis and a y-axis.
It is used in many applications, including math classes and real-world scenarios like maps.

The x-axis is a horizontal line, where values increase as you move to the right and decrease as you move to the left.
The y-axis is a vertical line, where values increase as you move up and decrease as you move down.
The point where the x-axis and y-axis intersect is the center of the graph, represented by the point (0, 0).

An ordered pair is a pair of numbers used to identify a point on the coordinate plane.
The first number in an ordered pair represents the x-axis value, and the second number represents the y-axis value.
The point (0, 0) is the center of the coordinate plane, where both the x-axis and y-axis values are 0.

To plot a point on the coordinate plane, first identify the x-axis value, then the y-axis value.
Only one point can have the same x- and y-axes values.
Example: The point (1, 3) is located one space to the right of the center and three spaces up.

When plotting a point with negative numbers, the point is located to the left and down of the center.
Example: The point (-1, -3) is located one space to the left of the center and three spaces down.
