<h3>hello!</h3>
We're given a point that the line intersects and its slope.
Let's use Point-slope:-

y1 = -5
m=-5
x1=-1


Convert to slope-intercept:-


Finally,

Cos9x - cos5x = -2sin2x.sin7x
sin17x - sin3x = 2sin7x.cos10x 
so f(x) = 

 =
 
 
        
        
        
Answer:
The answer is B.

The correct graph would be graph A. 
Since the line hits the y-axis at -1. And it goes down 2 and to the left 3 for each point.
