When a figure is translated to the left 6 units and up 5 units, the effect on the coordinates of the vertices can be described as follows:
- For the leftward translation of 6 units, you subtract 6 from each x-coordinate.
- For the upward translation of 5 units, you add 5 to each y-coordinate.
Therefore, the correct response is:
Subtract 6 units from each x-value and add 5 units to each y-value.
