Coordinate Plane: Plotting Points

  1. Always start at the Origin (0, 0)
  2. x-coordinate: Move right for positive (+), left for negative (-)
  3. y-coordinate: Move up for positive (+), down for negative (-)

Words: Coordinate plane (Plano cartesiano)Ordered pair (Par ordenado)Origin (Origen)Quadrant (Cuadrante)Reflection (Reflexión)
