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

The equation y = 0.10 x + 45 represents the cost y of a cell phone plan when x text messages are sent and received.

• The constant of variation is $0.10. + 45. This means that for every text message sent, you pay 0.10 + $45.

• There is no constant of variation. The cost does not vary directly with the number text messages sent and received.
