If you were asked to translate, I figure 3 units to laugh and six units up. How many units should you add to each y-coordinate?

To add 3 units to each y-coordinate, you would need to move the points vertically upwards by 3 units.

To translate a figure 3 units to the left and 6 units up, you will need to subtract 3 units from each x-coordinate and add 6 units to each y-coordinate. So, in this case, you should add 6 units to each y-coordinate.
