Graphing Proportional Relationships

Fill in the Blank

Determine if the information show a proportional relationship.

IF the relationship is proportional then express the answer in the form y=kx

IF the relationship is NON-proportional then express the answer as NO

On a graph, the x-axis is on the

• horizontal line

• vertical line

Multiple Select

Select 2 points listed that you see on this graph.

• (1,5)

• (5,1)

• (7,35)

• (35,7)

Multiple Select

What qualities must a graph have in order for it to be proportional? (Select ALL that apply)

• Must cross through the Origin, point (0,0)

• Must always be positive

• Must be a line

• Must be a straight line; has to be linear

The fact that it has the pair (0,0) mean that is does WHAT?


And that was one of the "requirements" for the graph.
