Answer:
C. 4/9
Explanation:
Parallel lines have equal slopes.
Since line l and line m are parallel, then their slopes must be the same.
![m_(l) =m_(m)](https://img.qammunity.org/2021/formulas/mathematics/college/t6nynuazprzalhhzhaqb0gjibjbq0lvtvn.png)
We know that the slope of line l is 4/9
![(4)/(9) = m_(m)](https://img.qammunity.org/2021/formulas/mathematics/college/8qfz121o64ppofiprgfvs69pfmsmfinqnx.png)
Line l has a slope of 4/9, therefore line m must also have a slope of 4/9.
The correct answer is C. 4/9
