Garis 6x-4y=7 ditrnslasikan titik (3,-1) lalu direfleksikan y = -x

(x , y) ditranslasi T [3 , -1] ➡️ (x+3 , y-1)

(x+3 , y-1) direfleksi y = -x ➡️ (y-1 , -x-3)

x" = y-1 , x"+1 = y

y" = -x-3 , y"+3 = -x , -y"-3 = x

6 (-y"-3) – 4 (x"+1) = 7

-6y-18 -4x-4 = 7

-4x – 6y – 22 – 7 = 0

(dikali -1)

4x + 6y = -29

semoga membantu 😉
