7-115.

The slope represents the change in height of a candle per minute.

The line is horizontal and shows no change in slope; therefore, the slope is zero and the candle is not burning.

The slope represents the gallons per month of water being removed from a well.

Using a slope triangle, find the distances of both legs of the triangle and solve in the slope formula.
