Question

Does anyone know how to do this? pls help

Answer 1

-3

Explanation:

If you reflect over the y-axis and then move 2 units to the left(x-2), then ABCD will be 3 units above EHGF. Since you need to move it down 3 units to map ABCD onto EHGF, you will need to do y-3, which is the same as y+-3

Answer 2

Answer is -3
Reason
When you reflect you do a mirror image.
Point D will be at (1, 2 )
Then you already know your new “x” direction is a -2, which moves your point D
To ( -1, 2). Now you want to move D down to match up with F, you will move down (y = -3)
So you flipped over the y axis, you translated over -2 and down -3. The figures will be on top of each other.
