Proportional Relationships Constant of Proportionality

Identify the constant of proportionality.

• k = 2x

• k = 2

• k = 4

• none (not proportional)

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

Identify the constant of proportionality.

• k = 2x

• k = 2
