When the acceleration of a particle is constant, it means that the slope of its velocity-vs.-time curve is constant, which results in a straight line. This is because acceleration is the rate of change of velocity with respect to time, and a constant acceleration means a uniform change in velocity with respect to time, resulting in a linear change.
