velocity
instantaneous magnitude of velocity
The rate of change in accelleration.
Area under velocity versus time graph(between two given instances of time i.e. two points on time axis) gives the displacement of the body( whose graph was plotted) between those two instances i.e. in that time interval. Area under velocity time graph can be found from definite integration if the graph is a curve. Note: Area under velocity versus time graph gives displacement not distance covered by body. Note: Area enclosed between the plotted curve and time axis is taken. For convenience time should be taken in the x-axis.
It tells you that the velocity of the body is not constant. There is acceleration or deceleration.
velocity
Assuming the graph is for displacement versus time, the motion should be constant velocity. If velocity versus time motion is constant acceleration
If you started at zero velocity, yes.
A vertical line on a velocity vs time graph is physically impossible.
instantaneous magnitude of velocity
The rate of change in accelleration.
Yes, acceleration is the slope of a velocity versus time graph.
Tangent of the slope at any point = velocity

The slope of the speed/time graph is the magnitude of acceleration. (It's very difficult to draw a graph of velocity, unless the direction is constant.)
A position time graph can show you velocity. As time changes, so does position, and the velocity of the object can be determined. For a speed time graph, you can derive acceleration. As time changes, so does velocity, and the acceleration of the object can be determined.If you are plotting velocity (speed) versus time, the slope is the acceleration.
