It means that either the distance is measured from the starting-line and the object is moving forward, or else the distance is measured from the finish-line and the object is moving backwards, because the distance is growing as time goes on. If the upward sloping diagonal line is straight, it means the speed is constant. (not velocity)
An upward sloping diagonal line on a velocity vs. time graph represents constant acceleration. The steeper the slope, the greater the acceleration.
The slope of a straight line tells the rate at which your variables are changing. In this case, it tells you how your velocity is changing over time, which in physics is how we define acceleration. If you graph the velocity of an object vs time when it is falling through the air, it gives to the acceleration due to gravity because that is the acceleration all objects fall at.
A position-time graph shows the relationship between an object's position and time. The position of the object is typically plotted on the y-axis, while time is on the x-axis. The slope of the graph represents the object's velocity, with a steeper slope indicating a higher velocity.
No, the slope on a position-time graph represents the object's velocity, not acceleration. Acceleration would be represented by the slope of the velocity-time graph.
This means your velocity is decreasing with time, or in other words, the object is slowing down.

Slowing down or decelerating
If you are analyzing speed with respect to time, then you are decelerating.

A straight line sloping upwards on a position-time graph indicates that the object is moving with a constant positive velocity. The slope of the line represents the velocity of the object.
That means the speed (the slope of the position-time graph) is decreasing.
On a graph of acceleration vs. time, during deceleration the line is below zero. On a graph of speed vs. time, during deceleration the line has a negative slope (sloping downward from left to right).
Deceleration can be symbolized as a negative value in an equation or graph, indicating a decrease in speed or velocity. It can also be represented by a downward sloping line on a velocity-time graph, showing a decrease in velocity over time.
The downward tend on a graph is called "decay".
The graph of a ball thrown vertically upward and coming downward without air resistance would be symmetrical around the peak. The velocity would be positive during the upward motion (accelerating upwards and then slowing down until it momentarily stops at the peak) and negative during the downward motion (accelerating downwards). The acceleration due to gravity would cause the velocity to increase in the downward direction until it reaches the initial velocity at the start.
