Explain in detail where the formula for the difference quotient comes from now that you know!  Include all appropriate terminology (secant line, tangent line, h/delta x, etc).  Your post must include text and some form of media (picture/video) to support.

The difference quotient has something to do with the slope formula.

The difference quotient formula comes from a point in x and then the height in the point that shows the functions. We can find the secant line with the 2 points with point x then the second with x+ a number in this case h because variables are easier when numbers are ambiguous and because we can note that the distance from x to x+# is h. 

To find the tangent line we need to use the difference quotient formula and get h to the limit 0 because tangent lines are derivatives.
