What is the equation of the line perpendicular to –x + y = 7 and passing through (-1, -1)?

-x + y = 2

-x – y = 2

x – y = 2

-x – y = 0

x + y = 0

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
