Answer:
Explanation:
Constructive feedback to your peer:
1. Correctness of the listed rule:
Your peer correctly identified that the pre-image is translated to the right by 4 units, indicated by the (x + 4) component of the rule. This means that the x-coordinate of each point in the pre-image is increased by 4 to obtain the corresponding x-coordinate in the image.
Adjustments needed in the rule:
2. Downward translation:
Your peer incorrectly stated that the pre-image is translated down by 4 units using the (y - 4) component of the rule. However, based on the given information, the correct downward translation is 5 units, not 4 units. Therefore, the (y - 4) component needs to be adjusted to reflect the correct downward translation.
3. Adjusted rule in words and coordinate notation:
The corrected official rule for the translation from the purple pre-image to the red image can be described as follows:
- Words: Translate the pre-image left 4 units and down 5 units.
- Coordinate notation: (x - 4, y - 5)
In this corrected rule, the x-coordinate is decreased by 4 units, representing the leftward translation, and the y-coordinate is decreased by 5 units, representing the downward translation.
By making these adjustments, the rule accurately describes the translation from the purple pre-image to the red image.
