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
