The Coordinate Graph

Vocabulary to know:


  • Ordered Pair or Coordinate - this is a point on the coordinate graph designated by a value of  x (horizontal) and a value of y (vertical).  They are always ordered alphabetically (x,y)
  • Quadrant - one of four sections on the coordinate plane created by the intersection of the x and y axis.  Quadrant I is the section where both the x and y are positive.  We go counter clockwise to name the remaining three quadrants.
  • Origin - (0,0) on the coordinate graph.  This is the point where the x axis crosses the y axis.
  • x-axis - horizontal number line
  • y- axis - vertical number line
