    Study Notes

    Reflection Over Axes

    • Reflection across the x-axis transforms a point (x, y) to (x, -y).
    • Reflection across the y-axis changes a point (x, y) to (-x, y).

    Examples of Reflection Across the X-axis

    • Reflecting (2,-3) results in (2,3).
    • Reflecting (5,7) gives (5,-7).
    • Reflecting (7,-8) yields (7,8).
    • Reflecting (-1,7) transforms to (-1,-7).
    • Reflecting (3,-7) leads to (3,7).
    • Reflecting (-2,-7) results in (-2,7).
    • Reflecting (-6,7) gives (-6,-7).
    • Reflecting (10,14) transforms to (10,-14).

    Examples of Reflection Across the Y-axis

    • Reflecting (-3,2) results in (3,2).
    • Reflecting (2,-3) over the y-axis yields (-2,-3).
    • Reflecting (-2,-5) leads to (2,-5).
    • Reflecting (-5,-5) gives (5,-5).
    • Reflecting (7,10) results in (-10,7).
    • Reflecting (7,8) transforms to (-7,8).
    • Reflecting (3,-7) leads to (-3,-7).
    • Reflecting (15,-2) gives (-15,-2).
    • Reflecting (-10,-11) results in (10,-11).
    • Reflecting (-5,3) transforms to (5,3).
