The value of the constant of proportionalityk is 1/9
It is defined as the relationship between two variables when the first variable increases the second variable also increases according to the constantfactor.
We have a proportional relationship is represented by the equation:
2x = 18y
After arranging the equation take the subject y
.....(1)
Comparing this equation to the equation y = kx
We will get the value of k which is the coefficient of x in the equation (1)
k = 1/9
Thus, the value of the constant of proportionalityk is 1/9
