Bab Persamaan GarisMatematika SMP Kelas VIII
ax + by = c, sejajar, (p, q)
ax + by = ap + bq
-3x + 4y = 5, sejajar, (-3, 6)
-3x + 4y = -3 . (-3) + 4 . 6
-3x + 4y = 9 + 24
4y - 3x = 33
Verified answer
(-3,6) dan 4y - 3x = 5m = - koefisien x / kofisien y
= - -3/4
= 3/4
garis sejajar memiliki gradien yang sama maka,
y-y1 = m (x-x1)
y - 6 = 3/4 ( x - (-3)) kedua ruas di kali 4
4y - 24 = 3(x + 3)
4y - 24 = 3x + 9
4y -3x -24 -9 =0
4y - 3x - 33 = 0
