How can the average rate of a change be identified for a function?

OpenStudy (igreen):

Average rate of change is the slope.. ANd if you have two points you can plug them into the slope formula: \(m = \dfrac{y_2-y_1}{x_2-x_1}\).

im ready

OpenStudy (secret-ninja):

So all I have to do is plug in the points in the function into the slope formula?

OpenStudy (anonymous):

@iGreen

OpenStudy (secret-ninja):

IGreen is already here.

OpenStudy (igreen):

Yep. Like if it gives you (2, 3) and (6, 9). ^ ^ \(y_1\) ^ ^ \(y_2\) | \(x_1\) | \(x_2\) Those will be your values..

OpenStudy (secret-ninja):

Thanks iGreen! :D *gives a medal*

OpenStudy (igreen):

Ty! :D
