2. The slopes of the lines in graph 1 can be interpreted as a useful quantity around the lab if you were working with water or one of these solutions. Explain the significance of the slope and how it might be used around the lab. Hint: look at the units and remember when a line is drawn it represents a sort of average as it places about half of the data above and below it due to random errors.
