the answer is C because according to the graph, the y-intercept is -6 and the slope is 3.
slope is rise over run, so find a point thats directly on a corner of the grid (i chose the y-intercept) and then count to see how many lines are between that point and the next one that's directly on the lines. (it's (1, -3)) making the slope 3/1 or 3
