Answer 3

Do you know the rule for reflecting a point across the y-axis? :)

Answer 4

no im so confused

Answer 5

It's (x, y) --> (-x, y)
So for example, if you have the point (2, 1) and you reflect is over the y-axis, it will become (-2, 1)
So do that with the three points of the triangle, A-B-C, to answer part A. :)

Answer 6

ok I think I got it @KamiBug
