Penjelasan dengan langkah-langkah:

13).

Q (x, y) → refleksi terhadap x = h → Q'(2h - x, y)

Q' = (2(2) - (-3), 6)

Q' = (7, 6) (A)

14).

R (x, y) → refleksi terhadap y = k → R' (x, 2k - y)

R' = (4, 2(-2) - 5)

R' = (4, -9) (B)

15).

P (x, y) → refleksi terhadap y = -x → P' (-y, -x)

P' = (-5, 4)

lanjut direfleksikan x = 2:

P" = (2(2) - (-5), 4)

P" = (9, 4) (D)

16).

A (x, y) → didilatasi oleh faktor skala k → A' (kx, ky)

A' = (-4x, -4y)

(4, -8) = (-4x, -4y)

(x, y) = (-1, 2)

Jadi, A = (-1, 2) (A)

17).

P (x, y) → didilatasi oleh [A (a, b), k] → P' (k(x - a) + a, k(y - b) + b)

P' = (1/2 (9 - (-3)) + (-3), 1/2 (-3 - 1) + 1)

P' = (3, -1) (Tidak ada opsi jawaban, mungkin bisa dicek)

18).

P' = (kx, ky)

(6, 9) = (2k, 3k)

k = 3

4k = 12

Sehingga,

Q' = (4kx, 4ky)

Q' = (36, 12) (A)

19).

A = (1, 1) → A' = (2, 2)

B = (1, 2) → B' = (2, 4)

C = (2, 2) → C' = (4, 4)

D = (2, 1) → D' = (4, 2)

Jadi, jawabannya A

20).

C = (-12, 3)

C' = (-1/3 (-12), -1/3 (3))

C' = (4, -1) (A)
