 If the slope of a tangent is:

 - positive/negative, that value on the derivative graph is also positive/negative, respectively
- - zero (e.g., linear equations), that value on the derivative graph is on the x-axis 
+ - zero, that value on the derivative graph is on the x-axis 

 Points of inflection on the original function become maximum/minimum points on the derivative graph.

+The derivative of a linear equation is always constant.
