HURRY HELP!!!!!!!!!
A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 8 inches.

For example, the point (0, 8) would represent a height of 8 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points)

Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points)
