How do you find the average rate of change with tables

The word "slope" may also be referred to as "gradient", "incline" or "pitch", and be expressed as:
      

A special circumstance exists when working with straight lines (linear functions), in that the "average rate of change" (the slope) is constant. No matter where you check the slope on a straight line, you will get the same answer.  Non-Linear Functions:When working with non-linear functions, the "average rate of change" is not constant.

The process of computing the "average rate of change", however, remains the same as was used with straight lines: two points are chosen, and  is computed.FYI: You will learn in later courses that the "average rate of change" in non-linear functions is actually the slope of the secant line passing through the two chosen points. A secant line cuts a graph in two points.

When you find the "average rate of change" you are finding the rate at which (how fast) the function's y-values (output) are changing as compared to the function's x-values (input).

When working with functions (of all types), the "average rate of change" is expressed usingfunction notation.

Idon’t feel like doing the math but you need to do 2.24 divided by 7
