Answer:
speed = m/s on y axis
time = s on x axis
when you calculate the slope you do y2-y1/x2-x1 right?
m/s/s become
, which is the unit of acceleration
On a speed vs time graph, if you see that the line is constant, then acceleration = 0 because there is no difference in speed, you are not acceleration or decelerating.
So in summary, it's acceleration
Hope that that answers your question
