Does this graph represent a function?

• Yes, because each x value has only one y value

• No, because the graph is not linear

• Yes, because the line goes through the origin

• No, because it does not pass the vertical line test

The graph above shows the price of games in dollars.  Is the graph proportional and how do you know?

• The graph is proportional  because it is linear.

• The graph is proportional because it is linear 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 linear and it does not pass through the origin.
