If we double each side of the second equation, 2x+y=8, we have 4x+2y=16.
Explain why the same (x, y)
pair that is the solution to the system is also a solution to this new equation. If needed, you can support your explanation by inventing a situation that the equations represent.

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8
