The points on this graph represent a relationship between x- and y
-values. Which statement about the relationship is true?
4 points in a straight line parallel to y-axis on a line graph.
It must be proportional because the points lie in a straight line.
It cannot be proportional because the x
-values are not whole numbers.
It cannot be proportional because a straight line through the points would not go through the origin.
It must be proportional because each time y
increases by 3, x stays the same.
