    Given:

    You move down 2 units and up 8 units.

    You end at (0, 4).

    To find:

    The starting point.

    Solution:

    Let the starting point be (x,y).

    You move down 2 units and up 8 units. So, the rule of translation is:

    (x,y-2+8)=(x,y+6)

    You end at (0, 4).

    (x,y+6)=(0,4)

    On comparing both sides, we get

    x=0

    y+6=0

    y=4-6

    y=-2

    Therefore, the starting point is (0,-2).
