Constant of Variation

Determine if there is a constant of variation. If so, explain what it represents. The equation y = 9.50 x represents the number of dollars y Marty paid for x movie tickets.

• The constant of variation is 9.50. This means that Marty paid $9.50 for each movie ticket

• There is no constant of variation. There is not a direct variation between the number of tickets and the total cost.

Determine if there is a constant of variation. If so, explain what it represents.

The equation y = 24 x represents the number of bottles of water y in x packages.

• The constant of variation is 24. This means that there are 24 bottles of water in each package.

• There is no constant of variation. The number of bottles varies per package.
