In such graphs the x-axis is usually (but not always) the time axis. The x-intercept represents the time(s) at which your position is at the starting point - either for the first time or later.
That means the speed (the slope of the position-time graph) is decreasing.
Nothing in particular. It certainly does not represent acceleration.
It means that the object was travelling away from or towards the point of reference with a velocity represented by the intercept at the start of the measurement, that is, at time t = 0.
A speed graph measures the distance devided over time. Acceleration graph measures the change in speed over time.
distance-time graph
Initial position is got by the y-intercept
A position-time graph, is one in which position is plotted on the y-axis and the time is on the x-axis. A position-time graph is similar to a distance-time graph, but direction of motion in the y-axis.
The velocity position time graph is rightward. This can change at anytime.
No. Slope of position/time graph is speed, or magnitude of velocity.Slope of speed/time graph is magnitude of acceleration.
The area of a position-time graph does not have a meaning. However, the area under a velocity-time graph is the displacement. Refer to the related link below for an illustration.

A girl walks along a straight path to drop a letter in the letterbox and comes back to his initial position. Her displacement-time graph. Plot a velocity-time graph for the same
The position at time t (and therefore the height of the p-t graph) will be the area under the v-t curve between time 0 and t.
The Average Velocity on a position time graph or a velocity time graph.
That means the speed (the slope of the position-time graph) is decreasing.
On a speed versus time graph, acceleration is represented by the line on the graph. If acceleration is constant, the line cuts through equally between the axis and starts from the zero point.
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.
