Question

The answer I got is not one of the options, and I am very confused, because now I don't know what to do?

If triangle ABC is reflected across line m, where will the new coordinates be located?
A’(-2, 4); B’(-7, 8); C’(2, 8)

A’(7, -8); B’(2, -4); C’(-2, -8)

A’(2, -4); B’(-2, -8); C’(7, -8)

A’(2, -4); B’(7, -9); C’(-2, -9)

Coordinate's I got:
A'(2,2), B' (7,-3), C' (-2,-3)

Can someone please clear this up for me?

Answer 1

A’(2, -4); B’(7, -9); C’(-2, -9)
I believe you did it correctly but over the wrong line. You were supposed to do it over line M and it looks like you did it over the X-axis.
