    Answer:

    y – 3x = -10

    Step-by-step explanation:

    Complete question

    Choose the equation below that represents the line passing through the point (2, -4) with a slope of 3

    The standard equation of a line in point-slope form is y-y0 = m(x-x0)

    Given

    x0 = 2

    y0 = -4

    alope m  = 3

    Substitute

    y – (-4) = 3(x – 2)

    y + 4 = 3(x – 2)

    y + 4 = 3x – 6

    y – 3x = -6 – 4

    y – 3x = -10

    Hence the required equation is y – 3x = -10
