Question

Write the notation (rule) to describe the translation. Point A(9, 4) is translated to point A'(3, 2). What is the translation rule?

A) (x, y) → (x - 6, y - 2)
B) (x, y) → (x + 6, y + 2)
C) (x, y) → (x - 2, y - 4)
D) (x, y) → (x + 2, y + 4)

Answer 1

The translation rule for moving point A(9, 4) to A'(3, 2) is (x, y) → (x - 6, y - 2).

Step-by-step explanation:

To determine the translation rule we need to look at how the x and y coordinates change from point A to A'. For the x-coordinate, the value decreases from 9 to 3 which is a change of -6. For the y-coordinate, the value decreases from 4 to 2, which is a change of -2. Therefore, the translation rule is (x, y) → (x - 6, y - 2).
