The points on this graph represent a relationship between two quantities. Which statement about the relationship is true?
It must be proportional because the points lie in a straight line.
It cannot be proportional because the y-values are not whole numbers.
It must be proportional because each time x increases by 2, y stays the same.
It cannot be proportional because a straight line through the points does not go through the origin.
The correct answer is: It cannot be proportional because a straight line through the points does not go through the origin.
Explanation: For a relationship to be proportional, it must pass through the origin (0,0), which means when x = 0, y must also equal 0. If the straight line connecting the points does not pass through the origin, then the relationship is not proportional, even if the points form a straight line.
