Study Notes
Coordinate Plane Terminology
-
Axes
- The coordinate plane features two number lines called axes: the x-axis (horizontal) and y-axis (vertical).
-
Coordinate Plane
- Comprised of an x-axis and a y-axis that intersect at the origin, dividing the plane into four distinct quadrants.
-
Coordinates
- A pair of numbers (x, y) that specify the precise location of a point on the coordinate plane.
-
Horizontal Axis
- Known as the x-axis, this is the horizontal number line extending left to right across the coordinate plane.
-
Line of Reflection
- Acts as the perpendicular bisector between a point and its reflected image, which can be any specified line including the x-axis or y-axis.
-
Ordered Pair
- This format (x, y) represents a point's location on the coordinate plane, with the x-coordinate presented first followed by the y-coordinate.
-
Origin
- The point (0, 0) where the x-axis and y-axis intersect, serving as a reference point in the coordinate system.
-
Quadrants
- The four regions created by the intersection of the axes, where each quadrant's location is influenced by the signs of the coordinates (positive or negative).
-
Vertical Axis
- Defined as the y-axis, it is the vertical number line that shows the distance from zero, known as the y-coordinate.
