Imagine that a line on a graph is approximately the distance y in feet a person walks in x hours. What does the slope of this line represent? How is this graph useful? Provide another example for your colleagues to explain.

The slope in this line represents the number of feet walked in an amount of hours. This is a very useful graph for knowing how many steps you may have taken in a day. For instance if you are trying to track how many steps you take for a study, or for weight loss, or for charity this can be an excellent graph to track your progress. The x and the y labels can be easily changed to represent different things. For instance, the x and y can be changed to represent the amount of tables built in a week. This can be useful for a carpenter to know how many tables he is producing on an average basis, and whether the amount done previously is going up or staying steady. This is also useful for the average family income, and tracking that data. If I wanted my colleagues to explain something it would be the number of candles that my friend burns in a year. I can tell you it is an obscene amount, so if you can explain that it would be great. You can let x be the year or months, and y be the candles.
