Final answer:
To find the coordinates of CDE across the horizontal line through y = -2, we need to reflect the y-coordinates of each point across the line y = -2. The reflected coordinates are: C'(-2, -2), D'(-2, -6), E'(6, -5).
Step-by-step explanation:
To find the coordinates of CDE across the horizontal line through y = -2, we need to reflect the y-coordinates of each point across the line y = -2.
For point C(2,2), the reflection point will be C'(-2, -2).
For point D(2,6), the reflection point will be D'(-2, -6).
For point E(6,5), the reflection point will be E'(6, -5).
