ANSWER
-2 shift the graph of the basic function down by 2 units.
EXPLANATION
The given cosine function is:

This equation can be rewritten as:

We compare this to

The effect d has on the graph is that, it shifts the graph up by d units.
If d is negative the graph shifts down by d units.
Since d=-2, the graph will shift down by 2 units.

Hey! :)
So when we write something in slope intercept form, all we're doing is solving for y. So let's do that with this equation!
-2x + y = 9
add 2x to both sides
y = 2x + 9
So C is your answer.
Please let me know if you need anything further explained!
Again, I'm really not sure if this is right, and please tell me where I got it wrong if I did.
