An equation has a proportional relationship if it can be written in the form y=kx where k is the constant of proportionality.
a.y=0.5x2 does not have a proportional relationship since it has the term −2 on the right side.
b.y=1,000x has a proportional relationship with a constant of proportionality of 1,000.
c.y=x+1 does not have a proportional relationship since it has the term 1 on the right side.
