tolong jwabkan ini yg isi lingkaran.. dgn caranya

b) Sejajar = nilai m sama
    x = -2y + 3 → y = -1/2x + 3/2 → m = -1/2
    y - y₁ = m(x - x₁)
    y - 3 = -1/2(x - (-4))
    y - 3 = -1/2x - 2
    y = -1/2x + 1 → 2y = -x + 2 → 2y + x - 2 = 0

d) 2y - 7x + 9 = 0 → 2y = 7x - 9 → y = 7/2x - 9/2
    m = 7/2
    y - y₁ = m(x - x₁)
    y - 3 = 7/2 (x - (-4))
    y - 3 = 7/2x + 14
    y = 7/2x + 17 → 2y = 7x + 34 → 2y - 7x - 34 = 0
