What is the equation of the graphed line in point-slope form?

1. y + 3 = 2 (x + 3)
2. y = 2(x + 3)
3. y + 3 = 2x
4. y – 3 = 2 (x – 3)

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
