Erin's airplane sketch, initially at (-2, 3), is translated 4 units down and 5 units right. The new coordinates of the nose become (3, -1), as correctly stated in option A.
Erin's airplane sketch has its nose at the coordinates (-2, 3). When she translates it 4 units down and 5 units right, each coordinate undergoes a corresponding change.
The vertical movement downward adjusts the y-coordinate by -4 (4 units down), and the horizontal movement rightward shifts the x-coordinate by +5 (5 units right).
Therefore, the new coordinates of the nose of the plane are obtained by applying these changes: (-2 + 5, 3 - 4), resulting in (3, -1). Option A, 3,-1, correctly represents the translated location of the nose of the plane after the specified movements.
