Answer: positive
Step-by-step explanation:
The slope of a line is given by:-
[tex]m=\dfrac{\text{rise}}{\text{run}}[/tex]
From the given picture, it can be seen that the rise in the line l is positive since the change in the y coordinates increases as we from left to right.
Similarly we can see that the run in the line l is positive since the change in the x coordinates increases as we from left to right.
By using above formula, the slope of line m is positive.
