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

• Yes and the COP is 2

• Yes and the COP is 1

• No because their is no COP

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

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
