HELP!!! Will give medal. Just need to get help or will fail my grade in math. A recent study claimed that in any given month, for every 5 text messages a boy sent or received, a girl sent or recieved 7 text messages. Is the relationship between number of text messages sent or recieved by boys proportional to the number of text messages sent or recieved by girls? Explain your reasoning using a graph on the coordinate plane.

    if the line is a straight line that crosses the origin, then yes, it is a proportional relationship. otherwise, it is not.
