Question

Figure ABC is to be translated to Figure A'B'C' using the rule (x, y) → (x−2, y+3). Triangle ABC on the coordinate plane with the ordered pairs for A as 1,1, B as 2,5, and C as 3,2.

Which coordinates will best represent point B'?
A (4, 2)
B (0, 8)
C (−1, 7)
D (5, 3)

Answer 1

( 0, 8 ) → B

Apply the given rule to the coordinates of point B (2, 5 )

thus B' = ( 2 - 2, 5 + 3 ) = (0, 8 )
