A student measures a distance-time graph that is a straight line with slope 3 m/s. After 6 seconds, what distance has the object traveled if starting at origin?

Explanation:
The slope of a distance-time graph represents speed, and a straight line through the origin indicates a constant velocity. Here the object moves at 3 m/s. After 6 seconds, distance traveled is 3 m/s × 6 s = 18 meters. Since it starts at the origin, the distance traveled equals the displacement from the origin, so the result is 18 meters.
