8.  acceleration =  = 1 unit .

9. acceleration =  = -1 unit.

10. acceleration =  = 0 units.

Explanation:

8. i) acceleration = velocity / time

  ii) In this figure velocity = time

  iii) therefore acceleration = = 1 unit .

9. i) acceleration = velocity / time

  ii) In this figure 4 = m + 5, therefore m = -1

     therefore velocity = (-0.5 time) + 5

  iii) therefore acceleration =  = -1 units.

10.) velocity is constant at 2

     therefore acceleration =  = 0 units
