Proportions Graphs/Tables

If a proportional relationship is graphed, which of the following is NOT true?

• It goes through the origin
• It is a straight line
• It has a constant rate of change
• It has a slight curve to it

To determine that a relationship is proportional, you must determine that the ratio y/x 

• varies
• is constant
• is zero

Is the relationship proportional?

• yes
• no

The relationship is not proportional because

• It does not go through the origin
• It goes through (1,1)
• It doesn't make a straight line

The relationship is

• proportional
• non-proportional

The relationship is 

• proportional 
• non-proportional

The relationship between x and y is 

• proportional
• non-proportional
