The given mapping for the translation of a rectangle is expressed as \((x, y) \rightarrow (x - 2, y + 7)\).
To analyze the translation:
- The \(x\) coordinate changes from \(x\) to \(x - 2\), which means it moves **2 units to the left** (since we are subtracting 2).
- The \(y\) coordinate changes from \(y\) to \(y + 7\), which means it moves **7 units up** (since we are adding 7).
Thus, the translation described is:
**a translation of 2 units to the left and 7 units up.**
