find the slope of a line L2 that is parallel to L1 where L1 is -4/3Find the slope but now L1 and L2 are perpendicular

Sagot :

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
