Question

What is the mean of Variable A? Express answer to one decimal place. Scatter plot on a first quadrant coordinate grid. The horizontal axis is labeled Variable A. The vertical axis is labeled Variable B. Points are plotted at (two, two), (two, eight), (four, three), (five, one), (six, three), (seven, five), (eight, six), (nine, two).

Answer 1

The variable A would most likely be your "independent variable."

This is just standard convention. Nothing is really saying that your independent variable can not be on your Y axis; it is just widely accepted to put your changing variable on the x and your dependent variable on the y axis.
