Since these two items are related, I can write them as an ordered pair. So, instead of working with the actual year, we are going to use a substitution. This is most likely the initial year or the year the house was built. Now let's take a look at one more example where all we are given is a graph. We must pay close attention to the graph in order to solve the problem. If the rate of change for interval A had remained constant throughout the whole marathon, how long would it have taken Karen to finish the marathon?
There are 26 miles in a marathon. Notice that interval is from the beginning to 1 hour. The first point is 0,0 and the second point is 1,6. During interval C, Karen took a break and stopped running. The three examples above demonstrated three different ways that a rate of change problem may be presented. Just remember, that rate of change is a way of asking for the slope in a real world problem. Real life problems are a little more challenging, but hopefully you now have a better understanding.
