The distance-time graph for the motion of an object moving with a constant speed is a __________.
Straight Line
On a distance-time graph, speed equals the slope:
\[\text{speed}=\frac{\Delta \text{distance}}{\Delta \text{time}}\]
Constant speed means equal distances are covered in equal times, so the slope is constant. A constant slope produces a straight line. A curve would indicate changing speed (acceleration); a horizontal line would indicate rest.
