The rate of change of a function is the change in the y-coordinates of a function divided by the change in the x-coordinates. If we have the graph of the function, we must extract two points and identify the coordinates of the points. Then, we apply the rate of change formula and ...
The slope of a line is the rate of change Rate of Change: The speed at which a variable changes over a specific period of time. It is often used when speaking about momentum, and it can generally be expressed as a ratio between a change in one variable relative to a corresponding chang...

The rate of change on a straight line is constant (always the same). Example: Find the slope of a line passing through the points (-2,3) and (3,-2). • If you graph the points, you can "count" the vertical and horizontal distances from one point to the other. The diagram show...
How do you find the average rate of change from a graph? To find the average rate of change from a graph over a specified interval, simply find the coordinates of the points at each end of the interval, and use those values in the slope formula to find the average rate of change betw...
The world is always in change. Concepts we need to study in this section is total change, average rate of change, percent change and percent rate of change.First we will consider the following profit function:P(q) = -2q2 + 400q – 5000 where q represents quantity of items sold.To...

One for you Average rate of change graphically We saw above that the average rate of change of ff over [a,b][a,b] is the slope of the line through the points on the graph of ff where x=ax=a and x=bx=b, and so we can calculate this rate from a graph. One for you Average...
