That should be a "direct variation" I believe.

A direct variation is one where the relationship can be graphed as a straight line.  If you double the amount of the input, the output is doubled.  Remember that a straight line has a constant slope.

Compute how many pages per hour Brandon read during each of the two reading sessions.  Is that rate the same for both?
