Point A(2, 3) is translated by the vector v = (4, -5). Find the coordinates of image point A'.
Answer and explanation
Correct answer: B. (6, -2)
- Step 1: Translation adds the components of the displacement vector to the coordinates: (x + a, y + b). Step 2. A' = (2 + 4, 3 + (-5)) = (6, -2). Answer: (6, -2). Why not the others: (6, 8) adds 5 instead of subtracting; (-2, 8) subtracts 4 from 2; (2, -2) fails to translate x.
