### Jessie's Linear Relation Scribe Post

6. Tessa and Vince go shopping at Bulk Bin. The graph shows the cost of banana chips.

A) Describe patterns shown on this graph.
B) Make a table of values from the graph.
C) Is it responsible to include a point on the graph that shows the cost of 250 g of banana chips? Explain

A) For every 100 Grams, it costs 60 cents. This graph is linear because it follows a pattern and the dots follow a straight line.

B)  g | 100  200  300  400
cents|  60   120  180  240

C) Yes, because 250 g will cost 150 cents or \$1.50

7)

A) For every cube, there are 2 cm added.
B) C| 1  2  3
Cm|  2  4  6

C) No, because the cubes cannot be halved.

8)

A) x | 1  2  3
y | 2  4  6

B) x | 1   2   3   4   5   6   7   8   9
y | 2   4   6   8  10 12 14  16  18

C) For every unit on the x axis, the y axis increases by 2.

D) If the value of the x axis is 9, then the value of the y axis will be 18.

9)

A)  H | 1    2    3    4    5
\$  | 15  30  45  60  75

B) The hourly pay is \$15/h

C) Yes, because 3.5 hours equals \$52.50

1. Well done Jessie. To make this post better you would have to include more of an explanation.
