So what you'd wanna do is your position at t equals two, and we know what our position at t equals two is. It was eight meters in the positive direction, so we could just call that positive eight meters. So it's going to be eight plus your change in position, which is going to be your displacement. And let's see, we can see this choice right over there, and that's what we would pick. This first option, v of seven, that just gives us our velocity at time seven, or exactly at seven seconds. Or another way is our rate of change of displacement at seven seconds, so that's not what we want. This one right over here, you have your position at t equals two, but then you have your change in position from t equals zero to t equals seven.
