It basically is already solved and can easily be graphed. Just start plugging in values to get your x,y points and make your line. The equation is basically in y=mx%2Bb form, the equation for a line.
f%28x%29=-2x-5
f%280%29=-5 (0,-5)
f%281%29=-2%281%29-5 f%281%29=-7 (1,-7)
f%282%29=-2%282%29-5 f%282%29=-9 (2,-9)
The graph would be as follows.
