Determine the slope of line l passes through points (6,-14) and (2,-4).
[tex]\begin{gathered} m=\frac{-4-(-14)}{2-6} \\ =\frac{-4+14}{-4} \\ =-\frac{10}{4} \\ =-\frac{5}{2} \end{gathered}[/tex]The line m is parallel to line l and parallel line have equal slope. So slope of line m is equal to -5/2.
Option 3 is correct.
