To translate a figure down 4 units and to the right 3 units, you adjust the coordinates of its vertices as follows:
- To move 3 units to the right, you add 3 to each x-coordinate.
- To move 4 units down, you subtract 4 from each y-coordinate.
Thus, the correct response is:
Add 3 units to each x-value and subtract 4 units from each y-value.
