persamaan garis yang melalui titik (4,-1) dan sejajar garis 2x-10y=3 adalah... tolong bantu kak! :')

Bab Persamaan Garis
Matematika SMP Kelas VIII

ax + by = c, sejajar, (p, q)
ax + by = ap + bq

2x - 10y = 3, sejajar, (4, -1)
2x - 10y = 2 . 4 - 10 . (-1)
2x - 10y = 8 + 10
2x - 10y = 18

x - 5y = 9
