Ordered Pairs
A set of two numbers arranged in a particular order. Written as (x,y), in which the x is the horizontal coordinate and y is the vertical coordinate.
Plot an Ordered Pair
To plot an ordered pair, you must start at the origin.
Hint: "Across the runway before you can takeoff."
Coordinate Plane: Graphing Ordered Pairs
Coordinate plane: The plane determined by a horizontal line (X-Axis) and vertical line (Y-Axis), intersecting at a point call the origin.
