Solution:
- The question says 8 units right. This means that the point will be 8 units to the right on the coordinate plane, which also means that the x-coordinate will be 8.
- The question also says 4 units up. This means that the point will be 4 units up on the coordinate plane, which also means that the y-coordinate will be 4.
Overall, the coordinate of the image point P' is (8,4).
