To find the reflection coordinates of the points in the image, it is necessary to identify the axis of reflection. Based on the grid, let's assume the reflection occurs over the y-axis (as it’s the most commonly reflected axis in this context).

Here are the current coordinates of the points $C$, $D$, $E$, and $F$ before reflection:

• $C(-6, -8)$
• $D(-2, -8)$
• $E(-2, -2)$
• $F(-6, -2)$

Reflection over the y-axis:

For a reflection over the y-axis, the rule is to negate the x-coordinate while keeping the y-coordinate unchanged. So, the new coordinates after reflection will be:

• $C' = (6, -8)$
• $D' = (2, -8)$
• $E' = (2, -2)$
• $F' = (6, -2)$

These are the reflected coordinates of the points across the y-axis.

Let me know if you'd like further details or clarification.
Here are some questions for expanding your understanding:

1. What would be the reflection rule for the x-axis instead of the y-axis?
2. How would you reflect the shape over the line $y = x$?
3. What transformations occur if both axes (x and y) are reflected simultaneously?
4. How can you find the coordinates after a rotation of 90 degrees about the origin?
5. How can translation be applied to this shape after reflection?

Tip: Reflections across different lines often involve different coordinate rules. Always identify the reflection line first!
