Need hel to figure this out Triangle TRS is
Triangle TRS is reflected across the line y = x. The result is AT'R'S', as shown below. (a) The arrows below show that the coordinates on the left are mapped to the coordinates on the right. Fill in the blanks to give the coordinates after the reflection. original coordinates - final coordinates T ( - 2 , - 4 ) - I'D R ( 6 , 1 ) - R'ID S (3, - 9) - S'ID (b) Choose the general rule below that describes the reflection mapping A TRS to AT'R'S'. O ( x, y) - (- x, - y) O (x, y) - (- x, y) O ( x, y) - (y, x) O (x, y) - (y, -x) O (x, y) - (x, - y) O ( x, y) - (-y, -x) O (x, y) - (-y, x)
