Answer:
-8/3.
Step-by-step 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.
[tex]\huge \boxed{- \frac{8}{3}}[/tex]
Perpendicular lines have opposite reciprocal slopes.
Start by finding the reciprocal. To do this, flip the numerator and the denominator. [tex]\frac{8}{3}[/tex]
Now, find the opposite of that. Add a negative sign. [tex]\displaystyle \boxed{- \frac{8}{3}}[/tex]
