When you walk into a dark room and turn the light on, do the electrons travel all the way from the switch to the light?

Yes

Explanation:

This is because for the light to come on, electric current has to flow through it which is due to electron motion. As the electrons move through the light, it turns electrical energy to light energy, so the light comes on.

  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.
