Proportional and Linear Functions

The graph shown is:

• linear function but not proportional.

• function, but not linear or proportional.

• proportional function.

• Not a function, linear or proportional.

The table shown is:

• Proportional because it goes through the origin.

• Linear, because there is a pattern.

• A function, because all of the x values are different.

• All of the above.

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.

Which of the tables shows a proportional relationship?

• A and B only

• B and C only

• A, B and C

• none of them
