• B

• C

• D

What is the unit rate in this proportional relationship?

• 60 miles/1 hour

• 120 miles/ 2 hours

• 1 mile/ 1 hour

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

Using the table above, determine the equation of the line.

• y = 5x

• y = 10x

• y = 1/5 x

• y = 1/10 x
