The constant of proportionality for this relationship is
Step-by-step explanation:
Proportional relationship is the relation between two variables that vary directly with each other
- If x and y are proportion, then y = k x, where k is the constant of proportionality
- If x and y are proportion, then
, where k is the constant of proportionality
∵ The equation is 3 y = 5 x
∵ x and y are proportional
- That means y = k x, where k is the constant of proportionality
∴ Put the equation in the form y = k x
- Divide both side by the coefficient of y
∵ The coefficient of y is 3
∴ Divide both sides of the equation by 3
∴ y = x
- The value is constant
∴ k =
∵ k represents the constant of proportionality
∴ The constant of proportionality =
