ANSWER IS

                    OPTION C. (  -6, 8)



reflection image of P(0, 0) , first across x = -3  , results in change of x value by, - 3 + ( 0 - 3)  and y value remains constant

reflection image of P(0, 0) , first across x = -3 

         =  ( - 6,0)

 reflection image of P(- 6, 0) then across y = 4?

value of x remain constant and y changes by  4 + 4-0=8

reflection image of P(- 6, 0) then across y = 4

       = (  -6, 8).................................................ANSWER


hope you understood..please message if you have any doubts...thank you
