Two resistors are hooked up in series to a 9 V battery. One of the resistors is 5 Ohms, and a voltage drop of 7 V is measured across it. What is the resistance of the second resistor?

  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.

i think the answer is a and b

i wish you luck
