A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 9 inches.

Oksanka [162]

The ordered pairs would be,

(1, 8.5)
(2, 8)
(3, 7.5)
(4,7)
(5, 6.5)
(6, 6)

I got the ordered pairs from the question since it stated that the length of the candle decreased .5 every hour. I just corresponded the hour to the length of the candle.

I hope this helped!
