Answer:

  r = 1/9

Step-by-step explanation:

First of all, solve the equation for r:

  y = rx

  y/x = r . . . . . . . divide by x

__

Since r is a constant, it will be the same for any corresponding pairs of x and y. It is convenient to choose both x and y as integers, as in the third table entry.

  r = y/x = 5/45

  r = 1/9 . . . . . . . . . reduced fraction

_____

<em>Additional comment</em>

It is not a bad idea to check to see that this works with other values of x and y. For the first line of the table, we have x = 11:

  y = rx = (1/9)(11) = 11/9 = 1 2/9 . . . . matches the table value
