<PRE><B>Question 254840</B>
Is the relationship
linear? Tell how you decided. Write the equation for each linear relationship

Thank you in advance! 
x 5 10 15 20 25 30
y 20 30 40 50 50 50
-------------------
As x increases 5, y increases 10, until you
get to x=25.  Since the increase from 25 to 30
does not have a corresponding increase of 10
in y the relation is not linear.
