Bab Persamaan Garis
Matematika SMP Kelas VIII

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

2x + 3y = 1, sejajar, (-4, 0)
2x + 3y = 2 . (-4) + 3 . 0
2x + 3y = -8
2x + 3y + 8 = 0

Answer 2

Verified answer

Garis 2x + 3y = 1
m1 = -2/3

syarat sejajar
m1 = m2 = -2/3

pers. garis melalui (-4,0) dan gradien -2/3 adalah
y - 0 = -2/3 (x + 4)
y = -2x/3 - 8/3
atau dapat ditulis
3y = -2x - 8
2x + 3y + 8 = 0
