tentukan persamaan garis yang melalui titik (2,4) dan sejajar garis x=3y+3

Bab Persamaan Garis
Matematika SMP Kelas VIII

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

x = 3y + 3
x - 3y = 3, sejajar, (2, 4)
x - 3y = 1 . 2 - 3 . 4
x - 3y = 2 - 12
x - 3y = -10
x = 3y - 10

x = 3y + 3
x - 3y = 3
gradien (m) = -1/-3 = 1/3

(y - y1) = m (x - x1)
(y - 4) = 1/3 (x - 2)
y - 4 = 1/3x - 2/3
-1/3x + y = 10/3
kali 3 semuanya
-x + 3y = 10
x - 3y = -10
