Coordinate Plane Basics
The coordinate plane is a two-dimensional plane that is divided into four quadrants by the x-axis and y-axis. The x-axis is the horizontal axis, and the y-axis is the vertical axis. Each point on the coordinate plane is identified by an ordered pair of numbers, called its coordinates.
The first number in the ordered pair is the x-coordinate, and the second number is the y-coordinate.
To plot a point on the coordinate plane, start at the origin (0, 0) and move along the x-axis until you reach the x-coordinate of the point. Then, move along the y-axis until you reach the y-coordinate of the point.
The point is located at the intersection of the two lines.
The coordinates of a point tell you its location on the coordinate plane. The x-coordinate tells you how far the point is from the y-axis, and the y-coordinate tells you how far the point is from the x-axis.
Reflections
A reflection is a transformation that flips a figure over a line. In geometry, reflections are typically performed over the x-axis or the y-axis.
To reflect a point over the x-axis, change the sign of the y-coordinate. For example, the reflection of the point (2, 3) over the x-axis is the point (2, -3).
To reflect a point over the y-axis, change the sign of the x-coordinate. For example, the reflection of the point (2, 3) over the y-axis is the point (-2, 3).
