The slope (technically, the slope of the tangent at each point) of a distance-time graph gives the instantaneous velocity.
Therefore, if the graph has a constant slope - i.e. it is a straight line - then that indicates a constant velocity (zero acceleration).
I believe that would be constant velocity. Note: be careful when talking about "speed" as opposed to velocity, as they are two different concepts in physics. Speed has no direction and is therefore always positive. Velocity on the other hand has a specific direction associated with it and can therefore be positive or negative. It is therefore said that speed is the magnitude or the absolute value of velocity. Be careful in the future.
Yes. The slope, or rate, is constant. The rate being represented is speed. If the slope is a negative constant, the object is losing distance (going towards) from the orgin at at a constant speed.
The graph is a straight line. Its slope is the speed.
Yes. Speed is the rate at which distance changes over time. In calculus terms v = dx/dt, or the slope of the distance vs. time graph. If the slope of the distance vs. time graph is a straight line, the speed is constant.
That's the distance covered.
It is 1 unit of distance per 1 unit of time.

At constant speed, the distance/time graph is a straight line, whose slope is equal to the speed.
It is 1 unit of distance per 1 unit of time.
It tells you that the speed of the object is not changing. The speed is represented by the slope in a distance vs. time graph, if slope doesn't change, speed doesn't.
Constant
No, it is a straight line passing through the origin.
The slope of a distance-time graph represents speed.
It is radial the velocity in a direction towards or away from a fixed point of reference (the origin) at a given time. The velocity time graph takes no account of motion in a direction across the radial direction.
