what is the slope of the given line?

anonymous · Answer

thats all it said

loser66 · Answer

I know, I guide you how to find the answer. The very first step is to find out the slope of the given line y = 1/2 x-8. What is it? 
Hint: the number in the front of x

anonymous · Answer

1/2

loser66 · Answer

good, so, the perpendicular line has the slope which is inverse of that number 
I mean, the slope of the required line is $\dfrac{-1}{1/2}=?$

do what now
