Let:
m1 = Slope of the line L1
m2 = Slope of the line L2
If two lines are parallel we can can conclude:
[tex]\begin{gathered} m1=m2 \\ where: \\ m1=-\frac{4}{3} \\ so: \\ m2=-\frac{4}{3} \end{gathered}[/tex]Answer:
-4/3
------------------------
If the lines are perpendicular, we can conclude:
[tex]\begin{gathered} m1\cdot m2=-1 \\ where: \\ m1=-\frac{4}{3} \\ so: \\ m2=-\frac{1}{-\frac{4}{3}} \\ so: \\ m2=\frac{3}{4} \end{gathered}[/tex]Answer:
3/4
