persamaan garis yang sejajar garis 4x - 3y - 7 = 0 serta melalui perpotongan garis x + y = 5 dan garis 2x - y = 4 adalah

Kelas 8 Matematika
Bab Persamaan Garis

2x - y = 4
x + y = 5
------------- +
3x = 9
x = 3

x + y = 5
3 + y = 5
y = 2

(3, 2)

ax + by + c = 0, sejajar, (p, q)
ax + by - (ap + bq) = 0

4x - 3y - 7 = 0, sejajar, (3, 2)
4x - 3y - (4 . 3 - 3 . 2) = 0
4x - 3y - (12 - 6) = 0
4x - 3y - 6 = 0
