Proportional vs. Non-Proportional

What 2 things are required for a graph to be proportional?

• Must go through origin and can be a straight or curved line

• Must be a straight line but can go through any point

• Must be a straight line and go through the origin

• Does not have be a straight line and can go through any point

Which best describes the equation?

y = 75x

• Proportional : COP is 75

• Nonproportional: COP is 75

• Proportional: There is no COP

• Non-Proportional: There is no COP

Is this graph proportional?

• Yes because it is a straight line and goes through the origin

• No because it is not a straight line but goes through the origin

• No because it is not a straight line and does not go through the origin

• No because it is a straight line but does not go through the origin

Is this table proportional or non-proportional?

• Proportional because the C.O.P. is the same for each column

• Non-Proportional because the C.O.P. is not the same for each column

• Proportional because there is no C.O.P.

• Non-Proportional because the C.O.P. is 4
