Answer:

the line falls

Step-by-step explanation:

Focus on the pair of points (-2, 0), (7, -5).  

As we move from the first to the second, the x-coordinate increases by 9 and the y coordinate decreases by 5.  Thus, the slop of this line is

       rise

m = ------- = -5/9

        run

As we move to the right from (-2, 0), the line falls (because the slope is negative).
