(4,-2) dan sejajar dengan garis 3× - 2y + 2 = 0

1 Jawaban

  • 3x - 2y + 2 = 0
    a = 3
    b = -2
    c = 2

    m = -a/b = -3/(-2) = 3/2

    Sejajar, m1 = m2 = 3/2

    Melalui titik (4, -2)
    (y - y1) = m(x - x1)
    (y - (-2)) = 3/2(x - 4)
    (y + 2) = 3/2(x - 4)
    2(y + 2) = 3(x - 4)
    2y + 4 = 3x - 12
    3x - 2y = 4 + 12
    3x - 2y = 16
