To find the initial position, Xo, we can simply compare the given equation with the general equation for position as a function of time:

X(t) = Xo + Vx * t

By comparing the given equation X = -3 + 0.8t with the general equation, we can see that:
Xo = -3
Therefore, Xo = -3

To find the velocity, Vx, we can use the coefficient of t in the equation for position as a function of time. In this case, the coefficient of t is 0.8, which is the velocity in this case.

Therefore, Vx = 0.8
