Bab Persamaan GarisMatematika SMP Kelas VIII
ax + by + c = 0, sejajar, (p, q)
ax + by - (ap + bq) = 0
4x + 8y - 16 = 0, sejajar, (5, -3)
4x + 8y - (4 . 5 + 8 . (-3)) = 0
4x + 8y - (20 - 24) = 0
4x + 8y - (-4) = 0
4x + 8y + 4 = 0 → persamaan garis h
cari gradien
m= -a/b
m = -4/8
m = -1/2
karena sejajar maka m1 = m2
titik (5,-3)
y - y1 = m(x-x1)
y -(-3) = -1/2 (x-5)
y + 3 = -1/2x + 5/2
---------------------------- ( kali dengan 2)
2y + 6 = -x + 5
2y + x +6 -5 =0
2y + x +1 = 0
