So I don't really understand the difference between a Secant line and a Tangent line.

What is the difference between them?

When are they supposed to be used/ can be used?

What do they represent?

How do you know if a line is tangent or secant?

If somebody can clarify these for me i'd really appreciate it! thank you :')

Also,

does anybody know what an average rate of change is? :(

i'm sorry if i keep asking questions i just don't understand any of this lol
