The shape is reflected over the y -axis. What are the coordinates of the point D′ ?

To reflect a point over the y-axis, we change the sign of its x-coordinate and leave the y-coordinate unchanged. Since D has coordinates (x_D, y_D), the coordinates of D' after reflecting over the y-axis will be (-x_D, y_D).
d= (5, 6)
If the point D has coordinates (5, 6), reflecting it over the y-axis will give us a new point D' with the coordinates (-5, 6).
