no
Is the graph proportional and how do you know?
The graph is proportional because it is straight.
The graph is proportional because it is straight AND passes through the origin.
The graph is not proportional because it does not pass through the origin.
The graph is not proportional because it is not straight AND it does not pass through the origin.
Is the graph shown proportional or non-proportional? Explain how you know.
proportional because it goes to the origin
non-proportional because it doesn't go to the origin
non-proportional because it is not a straight line
