Which shows the image of ΔRST after the rotation (x, y) → (y, –x)? Image A, B, C, D?(Tap image above)

Answer:Graph would be A.Step-by-step explanation:Given  : Graph.To find : Which shows the image of ΔRST after the rotation (x, y) → (y, –x).Solution : We have given that graph of triangle RSTCoordinates of R ( -3,1 ) and S(1 ,3) , T(-1, 8).By Reflection  rule  : (x ,y)  → (y, –x).Coordinates would be  R ( -2,1 ) →R' (1, 2).                                        S(1 ,3)  →S' (3, -1).                                        T(-1,7) →T' (7, 1).Therefore , graph would be A.
