D. $(x, y) \rightarrow(x+3, y-5)$
Solution
Solution Steps
To find the coordinate notation for a translation 3 units right and 5 units down, we need to adjust the x-coordinate by adding 3 and the y-coordinate by subtracting 5. This will give us the correct transformation for the given translation.
Step 1: Understand the Translation
To translate a point \( (x, y) \) by 3 units to the right and 5 units down, we adjust the coordinates as follows:
The x-coordinate is increased by 3: \( x' = x + 3 \)
The y-coordinate is decreased by 5: \( y' = y - 5 \)
Step 2: Apply the Translation to the Origin
Applying this translation to the origin point \( (0, 0) \):
New x-coordinate: \( 0 + 3 = 3 \)
New y-coordinate: \( 0 - 5 = -5 \)
Thus, the translated point is \( (3, -5) \).
Step 3: Identify the Correct Coordinate Notation
The coordinate notation for this translation is \( (x, y) \rightarrow (x+3, y-5) \).
