Answer 1

A"(-6, 3)

B"(-9, 0)

C"(-5, -1)

Explanation:

Answer 2

Explanation:

If a point (x, y) is translated by 4 units horizontally right and 1 unit upwards, coordinates of the image point will be,

(x, y) → (x + 4. y + 1)

Therefore, vertices of the image triangle ABC will be,

A(2, 2) → A'(2+4, 2+1)

→ A'(6, 3)

B(5, -1) → B'(5+4, -1+1)

→ B'(9, 0)

C(1, -2) → C'(1+4, -2+1)

→ C'(5, -1)

Then reflected across y-axis.

Rule for the reflection across y-axis will be,

(x, y) → (-x, y)

A'(6, 3) → A"(-6, 3)

B'(9, 0) → B"(-9, 0)

C'(5, -1) → C"(-5, -1)
