The of the line on a velocity vs. time graph represents acceleration.

~The slope of the line on a velocity vs. time graph represents acceleration.

Explanation:

~~Acceleration is equal to the ratio between the change in velocity of an object and the time taken:

a=\frac{\Delta v}{\Delta t}a=

Δt

Δv

On a velocity-time graph, this ratio corresponds to the slope of the line. In fact, \Delta vΔv corresponds to the increment in the y-value (the velocity), while \Delta tΔt corresponds to the increment in the x-value (the time), therefore their ratio corresponds to the definition of slope of the line.
