Unit 5 Review: Proportional Relationships

The number of trees and the number of apples are given in the table above.  Determine which statement below is correct.

• The table is not proportional because the unit rate is not constant.

• The table is proportional and the unit rate is 1/13

• The table is proportional and the unit rate is 13.

• 0

Two different proportional relationships are shown. One is represented by an equation and one with a table.

• The relationship modeled by the equation has the greater unit rate

• The relationship modeled by the table has the greater unit rate

• Both relationships modeled have the same unit rate
