1. The problem statement, all variables and given/known data
I am having trouble with the last question my teacher gave me. I have attached a picture. It is about instantaneous velocity. I did the same thing for all the other questions?

2. Relevant equations
average velocity = delta x / delta t

3. The attempt at a solution
I did 0-(-6)/(8-7) = 6

I figured it out. Apparently the tip of the line is not on 6 but on 5. I think that is not very visible.

Well done :)
When graphs have a fat line, the pointy-bits can cover a lot of ground. Always read to the middle of the line - use a ruler if you can.
For the future - please show your working. That would make how you are thinking clear so we can best help you.
Don't worry about looking stupid - we have all done stupider things than you: we understand ;)
