Question

△stu is a translation of △stu. write the translation rule.
(x, y) → (□, )

Explanation:

Step1: Find coordinates of a point

Take point \( U(-7, 4) \) and its image \( U'(-1, -1) \).

Step2: Calculate horizontal shift

Horizontal shift: \( -1 - (-7) = 6 \) (right 6 units).

Step3: Calculate vertical shift

Vertical shift: \( -1 - 4 = -5 \) (down 5 units).

Step4: Form translation rule

The translation rule is \( (x, y) \to (x + 6, y - 5) \).

Answer:

\( (x + 6, y - 5) \)
