Question 315645
Notice that m=-1 is the slope and b=-1 is the y-intercept. 

The easy way to graph this is to plot two points and make a straight line going through them, since it is linear. When x=0, y=-1. And when x=1, y=-2. Plot these two points and then make a straight line for the graph. Here is a picture: 

{{{ graph( 500, 500, -10, 10, -10, 10, -x-1) }}}
