Answer:

The cost depend on the number pencils, so the cost is the y and # of pencils is the x
Same as for question 7
To graph, the length depend on the time, so length is y, time is x
6. Linear
7. Not
X=-6
You get all the X to one side, and all the numbers to the other. Then divide. Work is shown in image below.
