The height (in centimeters) of a candle is a linear function of the amount of time (in hours) it has been burning. When graphed, the function gives a line with a slope of −0.6

Suppose that the height of the candle after 19 hours is
9.6 centimeters. What was the height of the candle after 13 hours?

2 answers

13 hours is 6 hrs less than 19 hours.
So, add 6(0.6) to the height.
The slope of the graph is –1. Which statement describes how the slope is related to the burning of a candle?
