Answer:
- constant of proportionality = 3
Step-by-step 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.
