horizontal axis on a graph is the
x-axis, goes from side to side
vertical axis on a graph is the
y-axis, goes from top to bottom
unrelated definition
two items that are not associated
related or proportional definition
two items that are associated
directly related or directly proportional definition
two items that are associated that when on one increases or decreases so does the other
