The vertices of  are A(2, 4), B(6, 0), and C(7, 2). Find coordinates of the image of  after the composition of the transformations in the order they are listed.
Translation: (x, y) → (x, y - 5)
Reflection: in the y-axis

The correct answer is: A’’(-2, -1), B’’(-6, -5), C’’(-7, -3)

Given the coordinates of triangle PQR are
P(2, 4), Q(6, 0), and R(7, 2)
Here, the translation rule is (x, y) → (x, y - 5).
A(2, 4) → A’(2, 4-5) = A’(2, -1)
B(6, 0)→ B’(6, 0-5) = B’(6, -5)
C(7, 2) → C’(7, 2- 5) =C’(7, -3)

Coordinate notation for reflection along the y-axis:
Multiply the x - coordinate by -1.
(x, y) →  (-x, y)
A’(2, -1)→  A’’(-2, -1)
B’(6, -5)→  B’’(-6, -5)
C’(7, -3)→  C’’(-7, -3)
