    B) Only (-3, 5)

    Step-by-step explanation:

    Slot in the options into the equation

    (-2, 4),

    Compare with (x, y)

    x = - 2, y = 4

    y = -3x - 4

    4 = (-3 * - 2) - 4

    4 = 6 - 4

    This is not true hence, option A is wrong

    Using (-3, 5)

    x = - 3, y = 5

    5 = (-3*-3) - 4

    5 = 9 - 4

    This is correct hence, option B is correct

    Option c is wrong because (-2,4) is not a solution to the equation

    Option D is wrong because option B is correct
