2. Definitions
Ordered Pairs – a set of “x” and “y” coordinates written in the form (x1, y1)
Coordinate Plane – a graph composed of the x-axis and y-axis that intersect at the origin (0,0). The plane is divided into four quadrants.

3. Coordinate Plane The y-axis is the vertical number line. Quadrant II
The x-axis is the horizontal
number line.

4. Ordered Pair
An ordered pair is a pair of numbers, such as (-3, 2) used to locate a point in the coordinate plane. H
2 is the y
coordinate
H (-3, 2)
-3 is the x
coordinate

5. Graphing and Identifying Ordered Pairs
Graph the Ordered Pair.
