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 understand this is not linear function but what is it asking me to do next.

  • math -

    change in y/change in x = constant slope if linear

    (30-20)/(10-5) =2

    (50-50) /(30-25) = 0 which is not 2
