Answer:
The correct option is C.
Explanation:
If a line passes through the point 
 with slope m, then the point slope form of the line is

It is given that the slope of the line is -1/7. From the graph it is clear that the line passes through the point (3,3).
Substitute x₁=3, y₁=3 and 
 in the above equation.

The point slope form of the given equation is 
.
Therefore the correct option is C.
