An image point has coordinates B'(7, -4). Find the coordinates of its Pre-image if the translation used was (x + 4, y + 5).

Answer 1

& please explain why

Answer 2

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

Answer 3

I understand it kind of thank you :]

Answer 4

Is it clear to you :)

Answer 5

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

Answer 6

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

Answer 7

Ohhh ok I get it ! Thanks

Answer 8

Just ask whatever you have in mind!
Sometime the solver don't want to much to confuse the asker!
