2-90.

Explain what the slope of each line below represents. Then find the slope and give its units.

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

The line is horizontal and shows no change; 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. Remember that the slope is the rise over the run, or the change in

*y*over the change in.
