To find where point B moves after we translate square ABDC, we first look at the starting point B, which has the coordinates (-1, 4). When we translate, we're moving point B.
We move it 2 units to the left. This means we subtract 2 from the x-coordinate (-1). So, -1 - 2 = -3.
Next, we move 4 units down. This means we subtract 4 from the y-coordinate (4). So, 4 - 4 = 0.
Now, we put the new coordinates together. After translating, point B' is located at (-3, 0). So, the new coordinates for point B' are (-3, 0).
