Question

at rest
distance
time
time is __ but doesnt change. no __
slow down
distance
time
the line curves down and gets less __. this shows a __ in speed.
*note:
distance
time
this graph does not represent slowing down, it represents returning to starting position.
speed up
distance
time
the line curves up and gets __.this shows an __ in speed.

Explanation:

For the "At Rest" situation, time passes but distance remains constant as there is no motion. In the "Slow Down" case, the slope of the distance - time graph decreases over time, indicating a decrease in speed. For "Speed Up", the slope of the distance - time graph increases over time, showing an increase in speed.

Answer:

At Rest: Time is passing but distance doesn't change. No motion.
Slow Down: The line curves down and gets less steep. This shows a decrease in speed.
Speed Up: The line curves up and gets steeper. This shows an increase in speed.
