You can put this solution on YOUR website!
When you add or subtract you are affecting the y value of every point.
--------
If you subtract a negative number you are adding to all the y-values and
the graph will move upward.
---------
If you subtract a positive number you are subtracting from all the y-values
and the graph will move downward.
----------------
