Average velocity from a position-time graph?

[xdeanna]

what is the object's average velocity during the entire interval?
..i know velocity would be the slope..but there's different slopes so what do i do?
does it have to do with instantaneous velocity?!

physics makes me sad. :(

Well there is no need to be. Average velocity is simply net displacement divided by time elapsed.

So..2m/s [N]? :D

For the complete path shown, yes.
