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.
