We know that

• The slope is -12.

,

• The point is (5, 3).

First, we use the point-slope formula.


y-y_1=m(x-x_1)

Where,


\begin{gathered} x_1=5 \\ y_1=3 \\ m=-12 \end{gathered}

Let's use these values to find the equation.


y-3=-12(x-5)

As you can observe, the signs are negative because the formula is that way.

Therefore, the answer is A.
