Question 62677
<b>graph the function.
f (x)= -2x - 5</b>

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:

{{{ graph( 300, 200, -6, 5, -10, 10, -2x-5) }}}
