Prop/non prop practice

The equation of a line is represented by y = 3x + 0. Kiki says the line shows a proportional relationship, while Donovan says the line shows a non-proportional relationship. Who is correct?

• Kiki is correct, because the line has a positive slope.
• Donovan is correct, because the equation is of the form y = mx + b.
• Donovan is correct, because the equation contains a zero.
• Kiki is correct, because the line passes through the origin.

Write an equation for this relationship.

• y=18x
• y=18.50x
• y=22.50x
• y=22x

What is the equation of the table?

• y = 11x + 5
• y = 11x - 5
• y = 12x + 27
• y = 12x - 27

Is this table proportional?

• Yes
• No

Write an equation for this situation.

• y=9.75x
• y=19.25
• y=19.25x
• y=9.5x

Which graph is proportional?

• A
• B
• C and D
• All of the graphs are proportional

Why does this graph show a non-proportional relationship?

• Because it is proportional
• It goes through the origin
• It does not go through the origin
• It is a straight line

Which equation represents a proportional relationship between x and y. 

• y = .25x + .25
• y = 14x -2
• y = x + 2
• y = x

• Table A represents a proportional relationship but Table B does not.
• Table B represents a proportional relationship but Table A does not.
• Both Table A and Table B represent proportional relationships. 
• Neither Table A nor Table B represent a proportional relationship.
