Okay, let's solve this one.
I would personally choose the coordinates \((1 , 14)\) and \((2 , 12)\), because they are going to make my life much easier than using coordinates that have decimals in them. Therefore, when we find the slope, we have zero rounding to do.
Now, we are going to use the formula \(m = \frac{y_2 - y_1}{x_2 - x_1}\) to find the slope, \(m\).
Plugging in our numbers, we get \(m = \frac{12 - 14}{2 - 1}\), which is equal to \(\boxed{-2}\).
