For which table(s) of values in Exercises 39–42 is the relationship
linear? Tell how you decided. Write the equation for each linear
relationship.
x 5 10 15 20 25 30
y 20 30 40 50 50 50
I do not think that this is a linear equation but I cannot determine the pattern so that I know why it isn't linear.

NOt linear. notice how y becomes constant at high x, that is not linear as the first.
