Which equation is most likely used to determine the acceleration from a velocity vs. time graph?

a. a = t over delta v.
b. m = StartFraction v subscript 1 - v subscript 2 Over x subscript 2 minus x subscript 1 EndFraction.
d. m = StartFraction x subscript 2 minus x subscript 1 Over v subscript 1 - v subscript 2 EndFraction.

The correct equation to determine the acceleration from a velocity vs. time graph is:

a. a = Δv / Δt

where Δv represents the change in velocity and Δt represents the change in time.
