What’s the answer for number 9 and explain how u got it for brainlest answer

An independent variable is something that  stands alone and isn't changed by another variable. So I think the correct answer is B:the same plane

Its not A because Distance can change. It's not C because you can always change the amount of something. It's not D because time can change as well.

HOPE THIS HELPED

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
