Answer:
--------------------------- HeyA --------------------------
Explanation :
- GiveN :
- C( 8 , -4 ) , D( 9 , -4 ) , E( 9 , 1 ) & F( 8 , 1 ) are the vertices of the given rectangle.
Reflection in the line y = k :
P( x , y ) ----------------------P'( x , 2k - y )
- C( 8 , -4 ) ----------------------C'( 8 , -4 )
- D ( 9 , -4 ) ----------------------D' ( 9 , -4 )
- E ( 9 , 1 ) ----------------------- E' ( 9 , -9 )
- F ( 8 , 1 ) ----------------------- F' ( 8 , -9 )
- C' ( 8 , -4 ) , D'( 9 , -4 ) , E' ( 9 , -9 ) & F'( 8 , -9 ) are the coordinates of the vertices after a reflection over the line y = -4 .
