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

1 answer

To reflect a point over the y-axis, we negate the x-coordinate while keeping the y-coordinate the same.

If the original point is D(x, y), the reflected point D'(-x, y) will have the same y-coordinate but the negated x-coordinate.

So, if the coordinates of point D are (x, y), the coordinates of point D' after reflecting over the y-axis will be (-x, y).
