Change to slope intercept form,
y=x-1
Plot the y-intercept first, (0,-1)

The slope gives you the change in y divided by the change in x.
Since the slope equals 1, then a change of 1 in x equals a change of 1 in y.
So to get the next point, start at (0,-1) and add (1,1)
(0,-1)+(1,1)=(1,0)
And continue doing that to generate more points.
(1,0)+(1,1)=(2,1)
(2,1)+(1,1)=(3,2)
You can then plot these points and finally the line through all of them.
