The true statement about the graph of f(x) is 
The graph of f(x) is a straight line that passes through the points (-5,0) and (0,3).
Start by calculating the slope (m)

So, we have:

Simplify

The equation of the line is then calculated as:

This gives

Open bracket

Express y as a function of x

Hence, the true statement about the graph of f(x) is

We can automatically rule out answer A, as short stories are not exclusively about the writers life.
That leaves B. C. and D.
B is incorrect as it is too vague in nature.
