Proportional Relations in Tables

Which of the tables shows a proportional relationship?

• A and B only

• B and C only

• A, B and C

• none of them

The table shown is:

• Proportional, because it is going up by 2 each time.

• Linear, because it is going up by two each time.

• Not a function, because 1 appears in the table twice.

• A function but non linear, because it doesn't start at zero.

What does Proportional table mean?

• straight line that does not go through the origin.

• A linear relationship represented by a table is a proportional relationship when the quotient of each pair of numbers is constant. Otherwise, the linear relationship is non-proportional.

What is the correct definition for proportional?

• if their corresponding elements have a constant ratio, which is called the coefficient of proportionality or proportionality constant. Two sequences are inversely proportional if corresponding elements have a constant product, also called the coefficient of proportionality.

• the quantitative relation between two amounts showing the number of times one value contains or is contained within the other.

• Proportional

• Non-Proportional

Does the table show a proportional relationship?

• proportional

• not proportional

• A

• B

• C

• D

The table is (a)   proportional.

• Yes

• No

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.

• The table is not proportional because it doesn't pass through the origin.
