The instantaneous velocity at 0.5 seconds will be the slope of the line connecting (0, -3) and (1, 10), which is 13 m/s.
The instantaneous velocity at 2.5 seconds will be the slope of the line connecting (1, 10) and (4, 5), which is -5/3 m/s.
The instantaneous velocity at 4.5 seconds will be the slope of the line connecting the points (4, 5) and (5, 5), which is 0 m/s.
The instantaneous velocity at 8.5 seconds will be the slope of the line connecting the points (8, -5) and (9, 0), which is 5 m/s.
