phi · Answer

The variables are the labels on the graph.  the label on the horizontal line is always listed first in a table.  the label on the vertical line is listed in a table second.

For example, in question 5,  you have number of pounds (or simply pounds)
and total cost  (or simply  cost)
the variables are pounds (along the horizontal direction) and cost along the vertical direction.  The graph shows how much a certain number of pounds cost.
