(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.
