This example explores the meaning of x- and y-coordinates and their notation, helping students understand points and lines in the coordinate system. It uses commands like Polygon, PointIn, Segment, Point, etc. Suitable for middle school and above students learning coordinate geometry.

GeoGebra Commands & Parameters

  1. Polygon((0, 0), (13, 0), (13, 6), (0, 6)) → AreaBee, f, g, h, i
  2. PointIn(AreaBee) → PointBee
  3. Segment((0, 0), (x(PointBee), 0)) → xCoord
  4. Segment((x(PointBee), 0), (x(PointBee), y(PointBee))) → yCoord
  5. Point(yAxis) → F
  6. Polygon(Zip[PixelsToPoint[Corner[1], Corner[3], Corner[5], A], A, {(pixelsLeft, pixelsTop), (pixelsLeft, y(Corner[5]) - pixelsBottom), Corner[5] - (pixelsRight, pixelsBottom), (x(Corner[5]) - pixelsRight, pixelsTop)}]) → borderBox
  7. Vertex(borderBox, 1) → cornerTopLeft
  8. Vertex(borderBox, 3) → cornerBottomRight
  9. Segment((0, 0), (0, y(cornerTopLeft))) → axisY
  10. Segment((0, 0), (x(cornerBottomRight), 0)) → axisX
  11. Corner(5) → appletSize

AI Drawing Prompt Reference

Draw a coordinate plane with a rectangle extending from the origin to 13 units along the x-axis and 6 units along the y-axis. Place a random point inside this rectangle, and from this point draw two perpendicular dashed segments: one down to the x-axis representing the x-coordinate, and one left to the y-axis representing the y-coordinate. Mark a point on the y-axis. Then draw the coordinate axes: a vertical y-axis from the origin upward and a horizontal x-axis from the origin rightward. The figure illustrates the meaning of x- and y-coordinates for a point in the plane.
