Yes. The relationship is proportional. This is because y is dependent on the changes of x with the constant rate of proportionality.

Direct proportion formula is:

y = kx

where k is the constant of proportionality.

In this case, k = 65 pages. x = number of hours. y = total pages read in x hours.

y         =      k       *       x
    65   =     65              1 hr
  195   =     65              3 hrs
  325   =     65              5 hrs
  585   =     65              9 hrs 
6500   =     65            10 hrs
