Question

Velocity-time graph is a straight line with positive slope. Acceleration is:

RankGuru · Accepted Answer

The acceleration $a$ is the derivative of velocity $v$ with respect to time $t$:
$a = \frac{dv}{dt}$. 
On a $v-t$ graph, this derivative corresponds to the slope of the line. 
If the graph is a straight line, its slope is constant. If the slope is positive, the derivative is positive.
Therefore, a straight line with a positive slope on a $v-t$ graph indicates a constant positive acceleration.
