Question

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

Explanation:

Step1: Determine the horizontal translation

Take a point, say \(X(0,1)\) and \(X'(-9,-7)\).
The horizontal change: \(-9 - 0=-9\). So we subtract \(9\) from the \(x\) - coordinate.

Step2: Determine the vertical translation

The vertical change: \(-7 - 1=-8\). So we subtract \(8\) from the \(y\) - coordinate.

Answer:

\((x,y)\to(x - 9,y - 8)\)
