1. The problem statement, all variables and given/known data

Hey guys, back again! This one's a real bugger on my online HW sheet :(:

1) The scale on the horizontal axis is 2 s per division and on the vertical axis 9 m/s per division. The particle has an initial position at 9 m.

[PLAIN]http://img20.imageshack.us/img20/3527/67419237.jpg [Broken]

What is the position of the particle after the first 2 s? Answer in units of m.

2. The attempt at a solution

1) For the first problem, since it was asking for the first 2 seconds and the units are by 2's, I looked at the "1" on the x axis... and since it was a velocity time graph, it was a constant velocity ?

I guessed 36 (9 x 4, and looking at the 1...), and I got it wrong. But now I'm thinking about it, and since it is constant velocity it may be 72 (x2) because it lasted 2 seconds? (I'm probably getting it confused with the position/time graphs we're also doing ><)
