To find the coordinates of the translated point \( Y' \), we start with the original point \( Y (-4, 1) \).
-
Translate down 3 units: This means we subtract 3 from the y-coordinate. \[ y' = 1 - 3 = -2 \]
-
Translate to the right 8 units: This means we add 8 to the x-coordinate. \[ x' = -4 + 8 = 4 \]
Now, combining these results, the coordinates of the translated point \( Y' \) are: \[ Y' = (4, -2) \]
Thus, the answer is (4, -2).
