Answer:
[tex]m_{l_{2} }[/tex] = 4
Step-by-step explanation:
( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )
( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
Slopes of parallel lines are equal.
~~~~~~~~~~~~
(- 3, 1)
( - 2, 5)
[tex]m_{l_{1} }[/tex] = [tex]\frac{1-5}{-3+2}[/tex] = [tex]\frac{-4}{-1}[/tex] = 4 ⇒ [tex]m_{l_{2} }[/tex] = 4
