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.

(3) Which table of value represent linelar relation shown.

A. X) 0 1 2 3 4         B. X) 0 1 2 3 4   C. X) 0 1 2 3 4  D. X) 0 1 2 3 4
     Y) 8 6 6 5 4             Y) 8 7 6 4 4        Y) 8 7 6 5 4       Y) 8 6 4 3 2
The answer for 3 is c.

Answer: c. expression, because equation has an equal sign and expression doesn't have an equal sign.

Answer: b. 3b, because the pattern is multiply the b by 3.

Answer: c 

The answer is c.

B) Yes, because the point of the line is in a straight line

C) Yes, because he can still work half the time and get paid half also.

A) The graph is about a grade 8 car wash, its about how much car they have cleaned and the price of it.

B) The pattern is $ = 10c, and the point is in a strait line.

C) A cost of one car wash is $10

D)

E) $150

A) The pattern on the graph is 3 units to the right and 9 units up.

8. Evaluate y = 7x + 3 using each value.

a. x = 1

 b. x = -4

c. x = 0

d. y = 17


















7. Evaluate each equation using the give value.

a. y = 5x - 3 when x = 6

b. y = x - 8 when x = 5

c. y = -5x when x = -2

d. y = x when y = 25

Yes it is a linear relation because it has the same pattern and goes in a straight line.

    B) Yes, because the points on the graph are straight. 

    C) Yes its possible. Klaus can only work for part of the hour. 

 Question 8

a) The graph shows how many cars were washed at the grade 8 car wash. 

b) The points are showed as a straight line meaning that its a linear relation. 

c) The cost for 1 car wash is $10.

d) table of values.

The correct answer would be letter "B". If we used that for base 1,2 and 3 it would work. 

Ex: 3 (1) = 3 

       3 (2) = 6

       3 (3) = 9

The graph relates to the letter C on the table of values. It's the answer because the numbers on the table of values are plotted on the graph.
