Question

A proportional relationship can be represented by an equation in the form y = kx,

where k is the constant of proportionality. For the equation 2x = 18y, what is the
constant of proportionality?

Answer 1

2x=18y

x=9y

x=9kx

k=1/9

Explanation:

A proportional relationship is a relationship between two quantities in which the ratio of one quantity to the other quantity is constant. A proportional relationship can be described by an equation of the form y = kx, where k is a number called the constant of proportionality.
