A rate of change tells us how one quantity changes in relation to another quantity. In a mathematical language, we can write this as follows:

For linear functions. the rate of change is the slope of the line. Thus:
FOR THE TABLE:
By taking two points we can get the rate of change, so let's take
:

FOR THE GRAPH:
Let's take
:

As you can see,
so <em>the ROC of the function given by the graph is greater than the ROC of the function given by the table.</em>
