The graph that shows uniform acceleration of a moving vehicle is a straight line with a positive slope. The slope of the line represents the acceleration of the vehicle. The higher the slope, the greater the acceleration.

Here is an example of a graph that shows uniform acceleration:

The x-axis of the graph represents time, and the y-axis represents velocity. The velocity of the vehicle is increasing at a constant rate, as indicated by the straight line. The slope of the line is the acceleration of the vehicle.
