Persamaan bayangan garis 2x + 3y - 5=0 oleh refleksi trhadap garis x=3 dilanjutkan translasi (-4,-2)adalah

2x + 3y - 5 = 0
refleksi thd x = 3
x' = 2.3 - x = 6 - x
x = 6 - x'

y' = y
Bayangan :
2x + 3y - 5 = 0
2(6 - x') + 3y' - 5 = 0
-2x + 3y + 7 = 0 ✔

translasi thd (-4,-2)
x' = x + (-4)
x = x' + 4

y' = y + (-2)
y = y' + 2

Bayangan akhir
-2x + 3y + 7 = 0
-2(x' + 4) + 3(y' + 2) + 7 = 0
-2x + 3y + 5 = 0 ✔
