Rewrite as y = 1 3 / ( x + 1 ), or ( y 1 ) = 3 / ( x + 1 )
This is simply the regular recriprocal equation, with the axies rescaled. The standard Y axis, representing X=0, is now marked x=-1. That is, the x-numbers are moved one to the right. The old X axis of 0,1,2,3 become -1, 0, 1, 2..
The old X axis, or Y=0 becomes y=1, and we have to rescale by a factor of 3. So the old Y coordinates 0, 1, 2, 3... become 1, -2, -5, -8...
And that's it.
