Slopes describe how fast the curve given by graphing one quantity versus another, rises and falls.
Slopes in daily life occur in the discussion of streets. A road or railway may rise three feet for every 100 foot traveled horizontally. In buying and selling, there may be an order charge plus a cost per unit for the total amount ordered. The cost per unit is a slope. When one quantity is proportional to second, the proportionality constant is also a slope.
