Question

An image point has coordinates B'(5, -6). Find the coordinates of its pre-image if the translation used was (x - 4, y + 5).

B(9, -1)
B(9, -11)
B(1, -1)
B(1, -11)

Answer 1

so you went (x-4, y+5) to get (5,-6)

to find where you got from you would reverse the operation , you are going backwards like this

(x+4 , y-5)

Does this make sense?

Answer 2

Making it easier,

(5,-6) --> (x+4)(x-5)

(5+4 , -6-5 ) is equal to ( 9 , -11)
