Exercise 54 Page 214

We are given the vertices of

△ A B C

and a translation rule.

(x, y) \to (x + 3, y - 1)

To find the coordinates of the vertices of the image, we need to add

3

to the

x -

coordinates and subtract

1

from the

y -

coordinates of the vertices of the preimage.

(x, y) A (2, - 1) B (0, 4) C (- 3, 5) \to \to \to \to (x + 3, y - 1) (2 + 3, - 1 - 1) (0 + 3, 4 - 1) (- 3 + 3, 5 - 1) \to \to \to \to (x^{'}, y^{'}) A^{'} (5, - 2) B^{'} (3, 3) C^{'} (0, 4)
