To translate the point A at (2, 7) left by 4 units, you need to subtract 4 from the x-coordinate while keeping the y-coordinate the same.
Starting point:
- A(2, 7)
Translation:
- New x-coordinate = 2 - 4 = -2
- New y-coordinate = 7 (unchanged)
So the new coordinates of point A will be (-2, 7).
Therefore, the correct response is (-2, 7).
