Audrey just lit a new candle and then let it burn all the way down to nothing. the
initial length of the candle was 15 inches and the candle burned at a rate of 1.5 inches
per hour. write an equation for the function l(t), representing the length of the
candle remaining unburned, in inches, t hours after the candle was lit.

h = 15 - 1.5 t

Step-by-step explanation:

In this example, I made h height.

For this situation, you would use y=mx+b.

If we use this formula, m would be slope. 1.5 is the slope and we are decreasing the size of the candle, which makes -1.5.

x would be t because that's the independent variable.

Since the initial height was 15 inches, 15 would be our starting point or y-intersept, which is b.

So if you put that together, you get h=-1.5t+15.

You can rearrange that to the answer above.
