To describe the effect on the coordinates of the vertices of a figure that is translated to the left 6 units and up 5 units, you would:
- Subtract 6 units from each x-value (because moving left decreases the x-coordinate).
- Add 5 units to each y-value (because moving up increases the y-coordinate).
Therefore, the correct response is:
Subtract 6 units from each x-value and add 5 units to each y-value.
