Quadrilateral GHJK has vertices G(2, 3), H(8, 2), J(6, 8), and K(3, 6). It is transformed according to the rule T(–4, –5). What
anyanavicka [17]
The answer:
explanation:

the transformation T(a, b) can be change the pre image to  the final image by following the rule as we explain below
if A(x, y) is a pre image, then A ' ( x', y') is its image, and x' = a+x, y' = b + y, where  because of T(a, b) transformation

in our case Quadrilateral GHJK has vertices G(2, 3), so <span>the coordinates of G”
can be found with

</span>T(-4, -5)  applied to  G(2, 3) ⇒ G' (-4 +2, -5+3)=G' (-2, -2)
 T(-4, -5)  applied to G' (-2, -2) ⇒ G"(-4-2, -5-2) =G"(-6, -7) 
the coordinates of G” are (-6, -7)
