9.The pattern can be represented by the formula b=4f, where b is the number of black dots and f is the figure number.

A) Make a table of values for the number b in figure 1 to 5.
B) Use the formula to determine the number of b in figure 60.
I did is multiply figure 5 by 2 to get 10 and get 40 black dots. Also I multiply figure 10 by 6 to get figure 60 so I multiply 40 black dots by 6 to det 240 black dots.

8.The graph shows the cost of a new drink called Zap and is \$3 each.
A)What is the price per can of Zap? Price per can of Zap is \$3.

B) Describe three patterns on the graph.
n=3c
Over 3 and up 1 each time.
3ct3 = n+1

C) If you placed a point ay (0,0), what would each coorinate represent.
O cans and 0 dollars. Because their is nothing that is half a can drinks.

7. To describe the graph in #3, you can say that x increased by 1, and y decreased by 1.
