Final answer:
The image of point B(-1,5) after the translation (x, y) = (x - 8, y + 4) is B'(-9, 9).
Step-by-step explanation:
The image of point B(-1,5) after undergoing the translation (x, y) = (x - 8, y + 4) can be found by applying the given transformation to the coordinates of point B. Applying the translation, we subtract 8 from the x-coordinate and add 4 to the y-coordinate. The new x-coordinate is -1 - 8 = -9, and the new y-coordinate is 5 + 4 = 9.
Therefore, the image of point B after the translation is B'(-9, 9).
