To reflect a point over the line y = 3, we need to find the new y-coordinate by subtracting the difference between the original y-coordinate and the line of reflection from the line of reflection.
The line of reflection is y = 3. The original y-coordinate of D is 6. The difference between the original y-coordinate and the line of reflection is 6-3 = 3.
The new y-coordinate of the image of D is 3 - 3 = 0.
The x-coordinate remains the same.
Therefore, the coordinates of the image of D are (3, 0).
The correct answer is (3, 0).
The coordinates of the vertices of triangleCDE are C(1, 4), D(3, 6), and E(7, 4). If the triangle is reflected over the line y = 3, what are the coordinates of the image of D?
