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 and add 5 units to each y-value.
This is because translating to the left means decreasing the x-coordinates, and translating up means increasing the y-coordinates. Thus, the correct transformation of the coordinates (x, y) would be:
New coordinates = (x - 6, y + 5)
