Any slope can be called a gradient. In the interstate highway system, the maximum gradient is 6 percent; in other words, the highway may never ascend more than 6 vertical feet over a distance of 100 feet. Any rate of change that's shown on a graph may have a sloped gradient. Suppose the graph's horizontal axis shows the passage of time and its vertical axis shows some activity; if the activity is happening very fast, then the gradient of the line on the graph will be steep, but if it's slow the gradient will be gentle, or gradual.

Examples of gradient in a Sentence
