Question
What is the image of point B (6, 2). Use the translation. 
- B’ (10, 6)
- B’ (10, - 6)
- B’ (-10, 6)
- B’ (10, 10)
The correct answer is: B’ (10, - 6)
Given, the co-ordinates of point B is (6,2).
The given translation to use is (x, y) → (x + 4, y - 8)
(x, y) → (x + 4, y - 8) - *
By substituting the co-ordinates of B in (x,y) in equation *.
(6, 2) → (6 + 4, 2 - 8)
= (10, - 6)
The image of point B after translation is (10,-6).
