Figure 2-41

gives the acceleration a versus time t for a particle moving along an x axis. The a-axis scale is set by as = 13.0 m/s2. At t = -2.0 s, the particle's velocity is 10.0 m/s. What is its velocity at t = 6.0 s?

what does the a-axis is "set" by as=13m/s^3 actually mean?

Is acceleration constant?

If acceleation is constant, then

v(6)=v(2)+a*t where t is six

Per the figure ( I was unable to post), the graph is a linear line, it doesn't mention that acceleration is constant.
