The distance-time graphs below represent the motion of a car. Match the descriptions with the graphs. Explain your answers 1. the car is stopped
2. the car is traveling at a constant speed
3. the speed of the car is decreasing
4. The car is coming back

real, smaller and upside-down.   so the answer should be b.

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
