The equation shown models the height of a candle after lighting it, where m represents the time the candle has been burning, in minutes, and h represents the candle's height, in inches.

Choose True or False that best describes each statement.

True

False

The slope of the equation is

(1/4) and the candle grows 1 inch every 4 minutes.

The candle has an initial height of 32 inches before lighting it.

32 minutes after lighting the candle, it will have a height of 0 inches.

The height of the candle is 25 inches exactly 28 minutes after lighting it.
