Complete this proportion table and graph the results. .

1. What is the slope of the graph?

   Hint (a):

   The table has been completed for you. The slope is the cost for one pound of nails.

   Pounds of Nails	Pounds of Nails, column 1$2$	Pounds of Nails, column 2$3$	Pounds of Nails, column 3$\bf 5$	Pounds of Nails, column 4$6$	Pounds of Nails, column 5$\bf 8$	Pounds of Nails, column 6$10$	Pounds of Nails, column 7$\bf 20$	Pounds of Nails, column 8$x$
   Cost ($)	Cost, column 1$\bf.50$	Cost, column 2$\bf 0.75$	Cost, column 3$1.25$	Cost, column 4$1.50$	Cost, column 5$2.00$	Cost, column 6$\bf 2.50$	Cost, column 7$5.00$	Cost, column 8$\bf0.25\boldsymbol x$

   
   One way to do this is to divide the cost for two pounds of nails in half.               

2. What does the slope tell you about the cost of nails?

   Hint (b):

   The slope tells you how much nails cost per pound.
