# Tangent line of instantaneous rate of change

I am currently experiencing some problems doing my review , for my quiz tomorrow! Basically, we are learning about instantaneous rate of change , which is section 2.2 (quiz on 2.1-2.2) . And then while I was going through the notes the last parts I had trouble on! Basically, these were the

Below:

## Words

b. Draw the tangent line at the data point for the time 1:17pm.

So the Instantaneous rate of change at Point P is the _________________ of the tangent line at point P.

If anyone can help me on these 2 problems , that would be greatly appreciated! Thanks a bunch for reading!
