Question

x	3	9	13	20
y	9	27	39	60

State whether the relationship between the variables in the table is a direct variation, an inverse variation, or neither. If it is a direct or inverse variation, write a function to model it.

​

Answer 1

y=3x

direct variation

y varies directly with x

if y=kx, it's a direct variation

k=3

9=3(3)

27=3(9)

39=3(13)

60=3(20)
