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
over the change in .
