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.
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.
Well, no. If the graph is a straight diagonal line, then the DISTANCE is steadily increasing, not the speed. This would translate into a constant speed. If the speed is steadily increasing, the object would travel more distance per unit time as we move along the horizontal axis. Meaning, the graph would curve upward.
A straight line on a distance - time graph represents a "constant velocity".

No. It means that the object is going at a constant speed.
The answer is TRUE because it is a straight line as the graph shows below. http://www.batesville.k12.in.us/physics/apphynet/Measurement/Images/d_vs_t2_graph.gif

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)

That the force that causes the acceleration is not constant.
If the distance/time graph is a straight line that makes a constant angel with the time axis, then the body's speed is constant, and is equal to the slope of the straight line (tangent of the constant angel).

The straight horizontal line would indicate constant speed.(NOT constant velocity. The velocity could very well be changing, but the graphdoesn't tell you anything about the direction of the motion, only that the speedis constant.)
