Question

The slope of the line below is -. Write the point-slope equation of the line using the coordinates of the labeled point.

Answer 1

B) y - 4 = -8/7(x - 4)

Explanation:

Point-slope form is

`y-y_1= (x-x_1)`, where m is the slope and (x₁, y₁) is a point on the line.

In our problem, m, our slope, is -8/7.

The point that our line passes through, (x₁, y₁), is (4, 4).

Plugging these in gives us

y - 4 = -8/7(x - 4)

Answer 2

B.

It uses the proper slope and has the 4's subtracted, which is proper for point-slope form.
