Question

What are the coordinates of the image of vertex F after a
reflection across the line y=-X?
(-1,-3)
(3,-1)
(1,3)
(-3,1)
G(-2. -3)
F(1.-3)
E -1, -5
H(2-5)

Answer 1

This takes too long to do. I will provide the steps.

For each point given, plug into the equation y = - x.

Point 1:

(-1, -3)

y = -x

y = -(-1)

y = 1

The first point reflected across the line y = - x is (-1, 1).

Do the same with the remaining points.
