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.

Answer:
Option (A)
Step-by-step explanation:
Slope of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by,
Slope = 
Form the graph attached,
Graphed line passes through two points (0, 1) and (-2, -2),
Therefore, slope of the line passing through these points will be,
Slope =
= 
Option (A) will be the answer.
