X-Coordinate


a list of two numbers that describes the location
of a point on a coordinate plane. (0,2)
shows the position left and right (horizontal) of
the coordinate plane. It is the first number in the
ordered pair.
Y-Coordinate

shows the position up and down (vertical) of the
coordinate plane. It is the second number in the
ordered pair.
Graphing Skills

Set of ordered pairs
(-3,2), (3,4), (0,0), (-5,-6)

Steps for graphing

1st graph the xcoordinate


Right or left
2nd graph the ycoordinate
