How Do You Graph Order Pairs

Each "ordered pair" describes one point on the graph. It's a pair of numbers.

-- The first number is the 'x'-coordinate of the point ... it tells how far the point
is left or right of the center.

-- The second number is the 'y'-coordinate of the point ... it tells how far the
point is up or down from the center. 

-- With that much information, you can find any point on an infinite piece of
paper that has no ends.  You only need an ordered pair of numbers, and
you need to know where the center of left-right is, and where the center of
up-down is.  Those lines are always drawn on the graph before you start
marking your ordered pairs.
