The graph shows the relationship of the amount of time (in seconds) to the distance (in feet) run by a jaguar.

Is the distance run by the Jaguar proportional to the time? Why or why not?

• Yes because the graph creates a straight line that passes through the origin.

• No because the graph does not create a straight line.

• No because the graph does not pass through the origin.
