Which transformations can be used to map a triangle with vertices A(2, 2), B(4, 1), C(4, 5) to A’(–2, –2), B’(–1, –4), C’(–5, –4

The triangles ABC and A'B'C' are shown in the diagram below. The transformation is a reflection in the line

. This is proved by the fact that the distance between each corner ABC to the mirror line equals to the distance between the mirror line to A'B'C'.
Even because even numbers are 2 4 6 8 etc
If he got 5 points in the first round and he needed at least thirty he would score 9 points in the next three rounds
18 ? am not really sure tho its kinda difficult lol
