Translation Coordinate Rules
Right h units • Left h units x ± h
Up k units • Down k units y ± k
Transformation Notation:
(x, y) → (x + a, y + b)
Add for right/up; subtract for left/down.

Challenge • Reverse Translation Bonus
A mystery point T was translated 4 units left and 5 units up, landing at the image T'(1, −2).
What were the coordinates of the original point T?
Reverse the rule: T( _____ , _____ )
Tip: To find the pre-image from the image, perform the opposite operation!

Common Student Misconceptions
- Reversing Axes: Applying horizontal shifts to the y-coordinate or vertical shifts to the x-coordinate.
- Integer Sign Errors: Adding instead of subtracting when moving left or down (e.g., in #4 calculating −1 + 4 = 3 instead of −1 − 4 = −5).
- Single Shift Neglect: In #2 and #5, changing both coordinates when only one direction was specified.
Grading Recommendation: 10 points (1 point per item). Award partial credit if rule is correctly written but arithmetic has sign error.
