Answer:

A(0, 8)

B(-5, 9)

Step-by-step explanation:

Given the rule of the transformation as;


(x,y)\rightarrow(x+3,y-5)

With the coordinates of the endpoints given as A'(3,3) and B'(-2, 4) obtained using the above transformation, to be able to determine the coordinates of the preimage, all we need to do is reverse the operation in the rule, that is, subtract 3 from the x value of the coordinates and add 5 to y-value of the coordinates as seen below;


\begin{gathered} A(3-3,3+5)\rightarrow A(0,8) \\ B(-2-3,4+5)\rightarrow B(-5,9) \end{gathered}
