    Answer:

    A. (–2, 4), one, three

    Step-by-step explanation:

    For a linear equation:

    y = a*x + b

    the point-slope form is:

    (y – y₁) = m*(x – x₁)

    Where we know that this line has the slope m, and passes through the point (x₁, y₁)

    In this case, the equation:

    (y + 2) = –1/3(x – 4)

    is already in the point-slope form.

    here we have:

    y₁ = -2

    x₁ = 4

    then the point is (-2, 4)

    m = -(1/3)

    m = -1/3 means that when we move 3 units to the right, we need to move one unit down. (or the inverse, we can move one unit down and 3 to the right)

    So, to complete the statement we have:

    plot the point (-2, 4),  move one unit down, and three units over to find the next point on the line.

    The correct option is A.
