Question

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

B(3, 1)
B(3, -9)
B(11, -9)
B(11, 1)

Answer 1

i did this for now :)) ill try others too

Answer 2

B

Explanation:

B'(7, -4)

Let the pre-image coordinates be (x,y)

Consider x-coordinate,

x + 4 = 7

x = 3

Consider y-coordinates,

y + 5 = -4

y = -9

pre-image coordinates is (3, -9)
