Name That Point

Remember that ordered pairs name locations on the coordinate plane. The first coordinate tells how many units to go left or right of the origin (0,0) along the x-axis. The second coordinate tells how many units to go up or down from the origin along the y-axis. For example, the ordered pair (−2,3) means go 2 units left and 3 units up from the origin.

  • On the Coordinate Plane Plotter, choose four coordinate points so that each point lies in a different quadrant.
    • First represent each point in the form (x, y).
    • Then plot your four points on the coordinate plane.
    • Identify in which quadrant each point lies.
    • Confirm with a partner that the quadrants you identified are correct.

  • What does the first number of the coordinate pair name?
  • Which is the negative direction on the coordinate plane on the x -axis?
  • Which is the negative direction on the coordinate plane on the y -axis?
  • Remember that (–2, –3) is in quadrant 3.
