Answer:

  • constant of proportionality = 3

Explanation:

You want to find the number of tickets required per game, given that the relationship is proportional and 9 tickets are required for 3 games.

Proportion

The equation of a proportional relationship can be written as ...

y = kx

where k is the constant of proportionality.

Constant

Solving for k, we have ...

k = y/x

Using a given ordered pair, we find ...

k = 9/3 = 3

The constant of proportionality is 3 (tickets per game).

__

Additional comment

Since the relationship is given as being proportional, we only need one (x, y) pair to find the constant of proportionality.
