Answer:
- J'(-4, -1)
- K'(-2, -5)
- L'(2, -5)
- M'(3, -1)
Step-by-step explanation:
Reflection over the line y=1 is equivalent to the transformation ...
(x, y) ⇒ (x, 2-y)
Then the transformed coordinates are ...
J(-4, 3) ⇒ J'(-4, -1)
K(-2, 7) ⇒ K'(-2, -5)
L(2, 7) ⇒ L'(2, -5)
M(3, 3) ⇒ M'(3, -1)
_____
You can do the arithmetic (as we have done above), or you can simply read the coordinates of the reflected points from the graph.
