Suppose △ABC has coordinates A(2, 3), B(5, 1), C(4, 4), and △ABC is mapped to △A′B′C′ by a reflection across the line y = 5 followed by a translation 1 unit down. select all the statements that are true about the coordinates of △A′B′C′.

Answer 1

A. A'(2, 2), B'(5, 0), C'(4, 3)
B. A'(3, 2), B'(6, 0), C'(5, 3)
C. A'(1, 2), B'(4, 0), C'(3, 3)
D. A'(2, 4), B'(5, 2), C'(4, 5)

A. A'(2, 2), B'(5, 0), C'(4, 3)
C. A'(1, 2), B'(4, 0), C'(3, 3)

Answer 2

AAAaannndd the bot gets it wrong yet again!

well, x will not change, so that eliminates B and C.
In fact, I suspect a typo, since none of the choices is correct.
for example, (2,3)→(2,7)→(2,6)

Answer 3

a and b
