Plotting and Reflecting Points on the Coordinate Grid

🎬 Video Tutorial

  • (0:01) Understanding the Coordinate Plane: The coordinate grid has two perpendicular axes, the x-axis (horizontal) and the y-axis (vertical), intersecting at the origin (0,0).
  • (0:34) Plotting Points Examples: To plot a point like (2,1), locate 2 on the x-axis and 1 on the y-axis, then mark the intersection.
  • (2:00) Reflecting Points: Reflecting over the y-axis changes the x-coordinate’s sign. Reflecting over the origin changes both signs.
  • (3:06) Reflecting Shapes: To reflect a shape, reflect each vertex (point) over the desired axis, then connect the points to form the mirrored shape.
