Does the table show a proportional relationship?

• Yes

• No

Proportional or Non-Proportional:
The graph does not pass through the origin. 

• Proportional

• Non-Proportional

Which of the following sets of ordered pairs represents a proportional relationship?

• <(0, 5)(1, 10)(2, 15) (3, 20)>

• <(3, 15)(5, 25)(8, 40) (12, 60)>

• <(4, 6)(8, 6)(2, 6)(5, 6)>

What is the y-intercept for the following graph and is it proportional or non-proportional?

• Proportional, b=1

• Proportional, b=-2

• Non-proportional, m= -1

• Non-proportional, b=1

Which equation shows a NON-proportional relationship of x and y?

• y = 5x

• y = 2.5x

• y = x + 3

• y = 1/2x

The graph shown is:

• A linear function but non proportional

• Not a function because it is not a straight line.

• Proportional because it goes through the origin.

• A function but not linear or proportional.

Which statement best describes the relationship of x and y in the table?

• Proportional

• Not Proportional

• They pass through the origin.

• They are linear and also pass through the origin.

• They are curved

• They have a negative relationship and pass through the origin.
