We can see that in this kind of graph, the dotted plots started from (8) and then went back higher but then back to (0). But as examining this, we would then already know the answer. Our answer would look like it would contain a negative symbol at the end. This would happen mainly because as we mentioned, the numbers are going back. And now that we have considered this, we would then have to see how much it would be going back.

We can see in the illustration below that the answer would most likely be (0.5) mainly because each step that it would take would be .5 of what it is.

A. -0.99
B. -0.5
C. 0.5
D. 0.99

And also, this would be -0.5 because it would be going back.
