Mathematics
Triangle A B C ABC is translated according to the rule ( x , y ) ( x + 2 , y 8 ) (x,y)rarr(x+2,y-8). If the coordinates of the pre-image of point B B are
( 4 , 5 ) (4,-5), what are the coordinates of B B^(') ?
( 2 , 3 ) (2,3)
( 1 , 9 ) (1,-9)
( 3 , 4 ) (-3,-4)
( 6 , 13 ) (6,-13)

Best Answer
Applying the given translation rule to the coordinates of point B B, we get:
B = ( B x + 2 , B y 8 ) = ( 4 + 2 , 5 8 ) = ( 6 , 13 ) B^(')=(B_(x)+2,B_(y)-8)=(4+2,-5-8)=(6,-13)
Therefore, the coordinates of B B^(') are ( 6 , 13 ) (6,-13).
So, the correct option is ( 6 , 13 ) (6,-13).
