The translation (x, y)(x+3,y-3) maps tuvw onto t'u'v'w. what translation maps t'u'v'w onto tuvw?
(x, y)(x+3,y-7)
(x, y)(x-7,y+3)
(x, y)(x+7,y-3)
(x, y)(x-3,y+7)

Mapping T'U'V'W' onto TUVW is just the backwards translations of TUVW to T'U'V'W'.

The translation (x + 3, y - 3) moves all x-coordinates 3 units to the right and all y-coordinates 3 units down.

So if we want to move the figure back to its original position, we do the opposite: move all x-coordinates 3 units to the left and y-coordinates 3 units up.
This is expressed as (x - 3, y + 3).
