& please explain why

anonymous · Answer

pre image B(x, y) = ( 3, -9)
Since B' (x +4, y+5) = (7, -4)

I understand it kind of thank you :]

anonymous · Answer

Is it clear to you :)

anonymous · Answer

its clear, my understanding of it is a bit fuzzy but after looking at it a little more i think i'll get it

anonymous · Answer

You match x + 4 = 7 --> x = 7- 4 = 3
y + 5 = -4 --> y = -4 -5 = -9
