Answer: A.
Explanation:
To find the slope we must find the change in y over the change in x. Δ
Or rise over run.
In the graph, we have two "good" points. (0, -6) and (4,0)
So for Δy 0 to -6 = -6
So -6 goes on top
Now Δx goes from 4 to 0 so the change would be -4.
So now it becomes
Since there are two negatives it becomes a positive.
Or simply put,
