Answer:
-2
Explanation:
To find the slope, you can do rise (change in y)/run (change in x). Take the points (0, 0) and (3, -6) There is a change of -6 in the y-direction (you can count on the graph) and a change of +3 in the x-direction. Using this, rise/over run, plug in -6/3 to get -2 as the slope.
