Learn how to calculate the average rate of change of a function by finding the slope of a secant line that connects two points on the graph. This line represents the equivalent trip taken at a constant average velocity, and its slope corresponds to the function's overall average rate of change over the given interval. By understanding this connection between secant lines and average rate of change, you can more easily interpret and analyze the behavior of functions on a Cartesian plot.
Be able to explain how average rate of change of a function corresponds to the secant line on a Cartesian plot of that function.
