In the provided image, the task is to reflect point $D$ over the $y$-axis.

To reflect a point across the $y$-axis, we change the sign of the $x$-coordinate while keeping the $y$-coordinate unchanged. Let's analyze the coordinates of point $D$ and reflect it.

1. Coordinates of $D$: From the graph, the coordinates of point $D$ appear to be approximately $(2, -2)$.

2. Reflection over the $y$-axis: When reflecting over the $y$-axis, the rule is: $(x, y) \rightarrow (-x, y)$ Applying this rule to the coordinates $(2, -2)$, the new coordinates will be: $(-2, -2)$

3. New Location of $D'$: After the reflection, the image of point $D$ will be located at $(-2, -2)$.

Let me know if you'd like more details, or if you have any further questions!

Here are some related questions:

1. How do you reflect a point over the $x$-axis?
2. What are the coordinates of point $B$ after reflecting over the $y$-axis?
3. What is the general rule for reflecting a point over the origin?
4. How do reflections affect the shape and size of a geometric figure?
5. Can you reflect a point over a diagonal line like $y = x$? If so, how?

Tip: When reflecting over the $y$-axis, only the sign of the $x$-coordinate changes, not the $y$-coordinate.
