Physics

I have a graph where the horizontal numbers are 0-9 which represents time (s) and the vertical numbers are 0 to -4, -2, 0, 2, 4, 6, 8 which represents position(m).
The question is: the position versus time for a certain object moving along the x-axis
The objects initial position is -2 m. Find the spontaneous velocity at 0.5 s. Answer in units m/s.
Find the instantaneous velocity at 2s. Answer in units of m/s.
