Answer:

-8/3.

Explanation:

If we have a line of slope m then the slope of a perpendicular line = -1/m.

So here the slope is - 1 / 3/8

= -8/3.

\huge \boxed{- (8)/(3)}

Perpendicular lines have opposite reciprocal slopes.

Start by finding the reciprocal. To do this, flip the numerator and the denominator.
(8)/(3)

Now, find the opposite of that. Add a negative sign.
\displaystyle \boxed{- (8)/(3)}
