Proportional Relationships & Constant of Proportionality

Does this table represent a proportional relationship?

• Yes

• No

Determine if each table represents a proportional relationship. If so, give the constant of proportionality.

• The table is not proportional because there is not a COP

• The table is not proportional

• The table is proportional and the COP is 2

• COP is 4

• COP is 1/4

• COP is 4x

• There is no COP

Write an equation for each table relating the x- and y-coordinates in the form y = kx. (find the COP for each order pair)

• y=7x

• x=7y

The constant of proportionality can be found by finding the __________  _____________.

• unit rate

• ratio rate

• proportion answer

• rational number
