There are 3 possible shapes to a Speed-Time graph:
Time is an independant variable and so is plotted on the axis, Speed is the dependant variable and so is plotted on the axis. The gradient of a graph is the change in divided by the change in . So for a speed time graph the gradient equals the change of divided by the change in which is . This means the steeper the line (the higher the gradient) the the acceleration of an object, giving a greater change of in a given time. The area under the graph is Speed × Time, which is equal to the the object has travelled.
