You can put this solution on YOUR website! graph the function.
f (x)= -2x - 5
The graph is a line because it's of the form y=mx+b.
To draw the graph you'll need two points, then you can draw the line going through them.
When x = 0 then f(x) = -2(0) - 5 = -5. So, (0,-5) is one point on the line.
When y = 0 then 0 = -2x -5 or 2x = -5 or x = -5/2. So, (-5/2,0) is a second point.
Now, draw a line between the two points. It looks like this:
(
