A point is reflected over the x-axis and then reflected over the y-axis. Will the coordinates after these two reflections be the same or different if the point is first reflected over the y-axis and then over the x-axis? Use an example to support your answer. Please help me!

    (x,y) -> (x,-y) -> (-x,-y)
    vs
    (x,y) -> (-x,y) -> (-x,-y)

    Hey, just try it
    y2 = -y1
    x2 = -x1
    ==========then
    x2 = -x1
    y2 = -y1 :)
