You can put this solution on YOUR website! First find any two points on the line.
(To find any two points:
when x = 0, y = -1, so (0,-1) is a point on the line
when y = 0, -x-1=0, solving for x we have x = -1, so (-1,0) is a point on the line.)
Next plot the two points.
Then draw a line that pass through the two points.
