check the picture below.

any parallel line to y = 12, like the red one and the green one there, will have the same slope as y = 12, what is the that slope anyway?

well, let's pick any two points y = 12 passes by, hmmmmm say 2, 12 and 4, 12


\bf \begin{array}{ccccccccc} &&x_1&&y_1&&x_2&&y_2\\ % (a,b) &&(~ 2 &,& 12~) % (c,d) &&(~ 4 &,& 12~) \end{array} \\\\\\ % slope = m slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{12-12}{4-2}\implies \cfrac{0}{2}\implies 0

I believe the answer would be -2/3.
