Proportional Nonproportional Functions Graphs

Why does this graph show a non-proportional relationship?

• It doesn't, it is proportional because it is a straight line
• It goes through the origin
• It does not go through the origin
• It is a straight line

 Is this table proportional or non-proportional?

• Proportional because the y to x ratio is a constant of proportionality. 
• Non-Proportional because the y to x ratio is not a constant of proportionality. 
• Proportional because the x to y ratio is a constant of proportionality. 
• Non-Proportional because the x to y ratio is not a constant of proportionality.
