math

I kind of owe someone a favor :P and I have no idea
A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 9 inches.
Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 9) would represent a height of 9 inches after 0 hours. Explain how you obtained the ordered pairs.
Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A.
Part C: If the rate at which the candle burned was 0.45 inches per hour instead of 0

  1. h = 9 - .5 t
    or if you insist on x and y
    y = 9 - .5 x

    (0,9) obviously
    (1,8.5)
    (2,8)
    (3,7.5) etc etc etc

    yes, there is one y for every x

    y = 9 - .45 x
