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

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

The equation that is most likely used to determine the acceleration from a velocity vs. time graph is:

a = m / (v subscript 1 - v subscript 2)

where 'm' represents the slope of the graph, and 'v subscript 1' and 'v subscript 2' represent the initial and final velocities, respectively.
