To describe the translation of rectangle \( MNPQ \) 4 units left and 3 units up, we can express the transformation using a coordinate rule.
If a point \( (x, y) \) represents a vertex of the rectangle, the transformation can be described as follows:
- Moving 4 units left means we subtract 4 from the x-coordinate.
- Moving 3 units up means we add 3 to the y-coordinate.
Therefore, the rule that describes this transformation is:
\[ (x, y) \to (x - 4, y + 3) \]
This means that for any point \( (x, y) \) in the rectangle, after the transformation, the new coordinates will be \( (x - 4, y + 3) \).
