Answer 2

(7, 1)


(−7, −1)


(−7, 1)


(7, −1)

Answer 3

any attempts so far? best is to start with the x = -1 reflection and see where the new coordinates of B would be

then from there, reflect across y = -3

lmk if you get stuck

Answer 4

-7, 1?

Answer 5

Answer 6

good attempt but not quite

Answer 7

that puts B' at the x-coordinate 7 not -7

then try drawing where y = -3 would be and try reflecting across that

Answer 8

7,1?

Answer 9

good
