is the closest, so that is the answer.
Answer:
(2+6)/2= 4 (x-coordinate of midpoint)
(7+3)/2= 5(y=coordinate of midpoint)
Post the picture so I can see
Answer:
Whatever the coordinates are it will be (x,y) all yo have to do is make y negative and thats a refelection
Step-by-step explanation:
Reflection in the x -axis:
The rule for a reflection over the x -axis is (x,y)→(x,−y) .
